Description

Receiving method of two-dimensional analog multi-beam receiving array

Technical Field

The invention relates to a receiving method of a two-dimensional analog multi-beam receiving array, such as a wireless communication technology, a mobile communication technology, a satellite communication technology and the like which utilize radio frequency, and can also be used in the application occasions of a receiving system of a phased array radar and radar detection.

Here, the radio frequency means a radio frequency including ultra high frequency/microwave/millimeter wave/terahertz.

Background

The traditional analog radio frequency phased array can only form a single wave beam, so that the receiver has low speed, low signal-to-noise ratio and short detection distance in search scanning. The analog radio frequency phased array single-beam technology is used for two-dimensional imaging, and has the defects of low sensitivity, single target, poor anti-jamming capability and the like.

The digital multi-beam radio frequency phased array receiver overcomes the limitation of an analog radio frequency phased array, can simultaneously generate two-dimensional beam signals, and is a theoretically ideal phased array receiving system. However, in practice, it is only possible to realize the system in a low frequency and narrow band, because in the case of a wide band, a high-speed analog-to-digital converter (ADC) satisfying nyquist sampling theorem is required, and it is difficult to achieve a small size and low power consumption. At higher application frequencies, such as microwave and millimeter waves, and even terahertz frequencies, it is difficult to integrate all of the rf devices, analog-to-digital converters, and digital interface circuits in a small area and space due to the antenna spacing being roughly on the order of half a wavelength. In addition, because no spatial filtering is performed before the ADC, a larger dynamic range and a larger number of quantization levels are required in order not to be affected by an interference signal, thereby greatly improving the requirements on the ADC design. A larger dynamic range ADC and a larger number of quantization levels means a larger power consumption. The large power consumption brings larger current pulses, causing higher interference pulse voltages, making the design of the ADC more difficult.

The large power consumption of the digital multi-beam radio frequency phased array receiver causes heat dissipation problems, and the device may be damaged when the device is overheated. The larger dynamic range and the larger number of quantization levels require more independent power supply networks, which means more package pins and larger chip package, and also pose a huge challenge to the design and integration of the system.

The most troublesome problem of digital multibeam rf phased array receivers is the wiring of the large number of digital transmissions and the resulting electromagnetic interference. There must be two ADCs per receive channel, an array of M rows and N columns requires 2MN ADCs and high speed interfaces. When the number of elements in the array is large, it is difficult to connect these high-speed signal lines directly to the central processing unit, especially at millimeter wave or higher frequencies. This is because in the implementation method of the phased array, the distance between the antennas is half a wavelength, and all components and high-speed digital lines need to be placed in the narrow area, which causes a great challenge. The resulting electromagnetic interference noise, coupled into the antennas of the array, directly reduces the sensitivity of the array.

The method of the digital multi-beam radio frequency phased array receiver is to form a plurality of beams pointing to users, so that the transmitting/receiving signals of the antenna array in a specific direction are added in a coherent mode, and the signals in other directions are offset.

Another approach to digital multi-beam formation is that of Massive MIMO. Massive MIMO can be considered as a form of beamforming in a broader sense. Massive refers to the number of a large number of antenna elements in an antenna array; MIMO refers to a multiple input multiple output system. Similar to the method of the digital multi-beam radio frequency phased array receiver, each antenna in the Massive MIMO antenna array is connected with a receiving channel, the receiving channel provides a digital interface, namely, radio frequency signals received on the antennas are converted into baseband signals in a down-conversion mode, then low-pass filtering is carried out, the baseband signals are directly digitized through an ADC (analog-to-digital converter), and all phase-shifting amplitude modulation is processed after being digitized. Massive MIMO in a practical system, the antennas and the ues, and the data transmitted in reverse direction are filtered by the surrounding environment. The signal may be reflected by buildings and other obstacles, and these reflections may have associated delays, attenuations, and directions of arrival. There may not even be a direct path between the antenna and the user terminal. These are solved directly by digitization, so that the subsequent computation is extremely large.

Massive MIMO also has the disadvantages of digital multi-beam rf phased array receivers if it employs a phased array type of compact integration. If the Massive MIMO adopts a non-phased array type distributed distribution mode, a larger area or space is needed, the power consumption of a digital signal processing part needed later is suddenly increased along with the increase of the number of array units, the system is more greatly realized, and the cost is greatly increased.

Disclosure of Invention

In view of the above technical problems, the present invention provides a receiving method for a two-dimensional analog multi-beam receiving array, in which a plurality of beams are generated, the method comprising:

a) Radio frequency signals received by the receiving antennas pass through the receiving array 201 of the analog multi-beam receiving unit 202, and the radio frequency signals received by the parallel antennas are converted into multi-beam phase-shifting and amplitude-modulating baseband signals 320 to be output;

b) Connecting the multi-beam phase-shifting amplitude-modulated baseband signals of all the multi-beam receiving units by using a tree-shaped transmission network 203 with a low-pass filtering characteristic to form a parallel two-dimensional analog multi-beam baseband IQ signal 409;

c) The parallel two-dimensional analog multi-beam baseband IQ signals 409 are further low-pass filtered and digitized through an analog-to-digital converter to form two-dimensional digital multi-beam 410 signals;

d) Signals of two-dimensional digital multi-beam 410 are distributed into a main beam and an auxiliary beam.

For the receiving method of the two-dimensional analog multi-beam receiving array, a plurality of main beams generated by the control of the system point to required information sources respectively; the auxiliary beams are divided into an auxiliary search beam 512 and an auxiliary tracking beam 511. The "desired source" herein refers to a useful source that needs to be received.

For the two-dimensional analog multi-beam receive array receive method described above, the auxiliary search beam 512 may be used for a scanning search to find a new transmit source.

For the above-mentioned receiving method of the two-dimensional analog multi-beam receiving array, the auxiliary tracking beam 511 can detect whether there is a better main beam position direction in the main beam tracking area 510 defined as the main beam, so as to update in real time or in the next working beat.

With the above-described receiving method of the two-dimensional analog multi-beam receiving array, the number and time-division layout of the auxiliary search beam 512 and the auxiliary tracking beam 511 can be dynamically controlled according to the receiving situation.

For the receiving method of the two-dimensional analog multi-beam receiving array, a multi-beam analysis method may be used to analyze and classify the main beam into an information source main beam and an interference main beam 121.

For the receiving method of the two-dimensional analog multi-beam receiving array, a multi-beam analysis method may be used to perform signal analysis on the source main beam, and divide the homologous source main beam 122 and the heterologous source main beam 123.

For the above-mentioned receiving method of the two-dimensional analog multi-beam receiving array, the optimization algorithm may be used to combine the main beams of the homologous sources in the multi-beam tracking and interference source eliminating unit 412 for all the independent source main beams 124, so as to suppress the main beam 123 of the heterologous source and the interference main beam 121.

For the above-described receiving method of the two-dimensional analog multi-beam receiving array, the method of generating analog multi-beams can be implemented by parallel phase shift and amplitude modulation on the analog baseband signal domain.

For the above-described receiving method of the two-dimensional analog multibeam receiving array, the method of generating analog multibeams can be realized by parallel phase shift and amplitude modulation on the analog radio frequency signal domain.

For the receiving method of the two-dimensional analog multi-beam receiving array, the method for generating analog multi-beams can be realized in the down-conversion process by changing the phase of the local oscillator signal.

For the above-mentioned receiving method of the two-dimensional analog multi-beam receiving array, the dividing threshold 611 can be dynamically adjusted to control the number of main beams, increase or decrease the complexity of the optimization algorithm, and dynamically balance between the received signal quality and the required minimum power consumption.

The invention is different from the traditional analog phased array receiver in that the former can generate a plurality of beams simultaneously, can receive information of a plurality of information sources simultaneously and inhibit coupling caused by interference sources, which cannot be realized by the latter.

The digital multi-beam radio frequency phased array receiver is different from the digital multi-beam radio frequency phased array receiver in that the digital multi-beam radio frequency phased array receiver can form multi-beams through an analog method, the number of necessary low-pass filters and analog-to-digital converters is greatly reduced, the problem of electromagnetic compatibility cannot be caused by connection, and cost and power consumption are greatly reduced; in the latter, 2 × mxn low-pass filters and analog-to-digital converters are used in an mxn array, and the digital connection is also very difficult, and the cost and power consumption are very high.

The invention is different from a Massive MIMO receiver in that the Massive MIMO receiver can form two-dimensional multi-beams through a simulation method, then generates a plurality of main beams through dividing a threshold value, combines the same information source and eliminates an interference source in the main beams with greatly reduced quantity, and greatly reduces hardware requirement, calculation cost and power consumption; the hardware overhead of the latter is similar to that of a digital multi-beam radio frequency phased array receiver, and the calculation cost required for solving the matrix equation is much larger.

Detailed Description

The invention aims at the technical problem, and provides a two-dimensional analog multi-beam receiving array system 200, which solves the problem of interference of an interference source in multipath communication or radar detection as shown in fig. 1.

Assuming a first dimension in a two-dimensional space of theta _x The second dimension direction is theta _y We need to receive multiple wanted sources, e.g. 101/102/101b, simultaneously with multiple interferers 103/104. Where it is required that the sources 101 and 101b belong to one information source but come from two or more different directions. The desired source 102 is not the same information source as the desired sources 101 and 101b, but is independent sources. We call sources 101 and 101b homologous sources, while mutually independent sources are heterologous sources. The method aims to simultaneously and respectively receive all required information sources, combine the information sources at the same time and furthest inhibit the influence from interference sources. These effects can cause degradation of SNR and EVM in the communication system, degrading the quality and bandwidth of the communication.

First, we generate a two-dimensional beam by simulating a multi-beam. As shown in fig. 2, the two-dimensional analog multibeam receiving array system 200 includes n rows and m columns of receiving arrays 201 of analog multibeam receiving units 202 having antennas, a tree transmission network 203, an analog-digital signal mixing processing unit 204, a digital signal processing unit 205, and a digital control signal interface 206.

The receiving array 201 is used for receiving the radio frequency electromagnetic wave incident in parallel through the antenna array to be converted into a radio frequency electric signal, then generating K independent two-dimensional analog multi-beams through the n rows and m columns of analog multi-beam receiving units 202, and outputting the K independent two-dimensional analog multi-beams in the form of orthogonal component I/Q and differential baseband signals.

Two-dimensional simulation of radio frequency formation of multiple beams, which is to be realized

sin(wt+b)＝sin(wt)cos(b)+cos(wt)sin(b)

Is weighted. Where w is the angular frequency of the radio frequency carrier frequency and b is the angle of the phase shift.

When we want to perform two-dimensional analog beamforming on the analog multibeam receiving unit 202 of the linear receiving array 201, b can be written as:

b＝nΔθx _i +mΔθy _i +b0(n,m)

where n and m are the addresses of the receiving units 202 in the array, Δ θ x _i Is the phase shift angle of the ith beam in the x-direction, m Δ θ y _i Is the phase shift angle of the ith beam in the y-direction, b0 (n, m) is the intrinsic phase shift angle of the cell, and i =1,2,3, \ 8230;, K.

One method of achieving analog multi-beam formation is to do vector modulation at radio frequencies. Simulating the multi-beam receiving unit 202, amplifying the radio frequency signals received by the antenna, forming orthogonal radio frequency vectors, i.e. orthogonal radio frequency signals with a phase difference of 90 degrees, weighting the required phases by taking a sine function and a cosine function respectively, and finally realizing

sin(wt+b)＝sin(wt)cos(b)+cos(wt)sin(b)

The physical implementation is done by a plurality of parallel multi-beam phase-shift modulators 311 and parallel down-converters 312m, see fig. 3 (b).

Another method for analog multi-beam forming implementation is shown in fig. 3 (c), which is implemented by parallel down-conversion 312m, and requires independently controllable multiphase quadrature local oscillator phase shift signals 313m to clock the parallel down-conversion 312 m. This requires the generation of multiple phase quadrature local oscillator phase shifted signals 313m, which may also be generated by linear vector synthesis using the quadrature phase of the original local oscillator LO, to achieve, for example, sin (w) _Lo t+b)＝sin(w _Lo t)cos(b)+cos(w _Lo t) operation of phase shifting sin (b), in which w _Lo Is the local oscillator frequency.

Another approach to analog multi-beamforming implementation, see fig. 3 (d), can be achieved by parallel phase and amplitude modulation of the orthogonal baseband signals. The rf input signal 302 is amplified by the lna 310 and then converted to an orthogonal baseband signal by the parallel down-converter 312; the parallel phase-shift modulator 311m performs vector modulation on the orthogonal baseband signal to shift the phase, thereby realizing

sin(Ωt+b)＝sin(Ωt)cos(b)+cos(Ωt)sin(b)

Where Ω is the baseband angular frequency. Then, amplitude modulation is performed by an amplitude modulator, and a multi-beam phase-shifting and amplitude-modulating baseband signal 320 is output.

Regardless of which method is employed, analog multi-beam receiving element 202 may be represented by the symbol of fig. 3 (a); analog multi-beam reception 202 requires multi-beam phase and amplitude modulation control signals 321 from multi-beam controller 404 in digital signal processing unit 205 to analog multi-beam reception 202 via digital control signal interface 206.

A two-dimensional separable receive array and digital signal processing unit architecture 400 is shown in fig. 4, which includes a receive array 201, parallel analog multi-beam baseband IQ signal lines 401 connected at the array level to outputs of M columns of N rows of analog multi-beam receive units 202, a tree transmission network 203, an analog-digital signal mixing processing unit 204, and a digital signal processing unit 205. Parallel analog multibeam baseband IQ signal lines 401 partially connect the outputs of the receiving units 202 according to the beam order of the multibeam output by each analog multibeam receiving unit 202, while the tree transmission network 203 partially connects, or globally connects, the outputs of all the beams in the beam order to form a parallel two-dimensional analog multibeam baseband IQ signal 409, which, if IQ, has

IQ＝[(i ₁ ,q ₁ ),(i ₂ ,q ₂ ),(i ₃ ,q ₃ ),…,(i _K ,q _K )]

Wherein (i) _i ,q _i ) Is the generation of the ith beam.

The tree transmission network 203 may be implemented as a one-dimensional 2-element tree structure, for example, a partial connection in the vertical direction is made at the output of one dimension, and then a full connection of the one-dimensional 2-element tree structure is made in the horizontal direction. The tree transport network 203 may also be implemented as a two-dimensional 2-element tree structure, i.e. the beam outputs of the receiving units 202 of the array are connected in sub-blocks.

The tree transmission network 203 also presents the characteristic of low-pass filtering, and is cascaded with a low-pass filter in the following analog-digital signal hybrid processing unit 204 to synthesize the whole required characteristic of low-pass filtering, and performs low-pass filtering on baseband signals to remove out-of-band interference signals, so as to ensure that the ADC can normally work under the condition of satisfying nyquist sampling without aliasing distortion. The analog-digital signal mixing processing unit 204 includes 2K Low Pass Filters (LPF) cascaded to 2K analog-to-digital converters (ADC) because in quadrature output form, one beam is represented by two components. The output signal of the analog-digital signal mixing processing unit 204 is a two-dimensional digital multi-beam 410.

The digital signal processing unit 205 includes a multi-beam controller 404, a multi-beam analyzing unit 411, a multi-beam tracking and interferer cancelling unit 412, and a control unit 416.

The multi-beam analyzing unit 411 divides the two-dimensional digital multi-beam 410 signal according to a specific division threshold 611 according to the two-dimensional digital multi-beam 410, and if the signal amplitude is larger than the division threshold 611, keeps its output as a main beam. If the main beam is not defined before, a main beam is redefined, the characteristics of the information source are detected through digital demodulation, and the main beam is identified. The source characteristics may indicate the source information of the source, which may be different in different applications and standards, such as the need to solve the channel state information code in 5G communication, for example, to obtain the satellite identity/identification code in satellite communication, such as the MAC address code in IP-based digital communication.

The multi-beam analysis unit 411 quantizes the detected plurality of desired sources 101/102 and plurality of interferers 103/104 on a two-dimensional beam grid, and sets the source and interferer larger than the splitting threshold 611 on the two-dimensional digital multi-beam signal 410 as the main beam.

The multi-beam analyzing unit 411 performs signal analysis and classification on the main beam, and divides the main beam into an information source main beam and an interference main beam 121. The multi-beam analysis unit 411 performs signal analysis on the source main beam to divide the source main beam 122 into a source main beam 122 and a source main beam 123.

The multi-beam tracking and interferer cancellation unit 412 may be implemented using a digital signal processor DSP, or may be implemented using a programmable array FPGA, or a CPU/GPU. One of the tasks of the multi-beam tracking and interferer cancellation unit 412 is to track, i.e. check, whether the already defined position of the main beam is the optimal position, i.e. the position of the grid intersection reaching the maximum amplitude, in the tracking zone around the main beam, see fig. 5. If the current position is not the position of the maximum amplitude, updating to the position of the maximum intersection point; if the current position is already the position of maximum magnitude, the current position is maintained.

Another task of the multi-beam tracking and interferer cancellation unit 412 is interferer cancellation, i.e., source main beam is optimized to minimize interference to it by all interfering main beams 121 and the heterologous source main beam 123. For a desired source, although the associated receiving main beam is directed toward it, there will still be interference from other sources from other directions, including interfering main beam 121 and heterologous source main beam 123. Of course, there may be a main beam 122 from a homologous source in a different direction. The generation of the main beam 122 of the same source may be from a radio frequency signal transmitted from a transmission source, blocked or reflected, or may be directly transmitted from a different direction.

If the output of main beam B1 contains interference from other sources, see fig. 6, B3 and B4 are two interference main beams 121, B2 is a main beam 123 from a different source, and B1B is a main beam 122 from a different source. For the main beam B1, its output can be expressed as

Y1＝a11B1+a12B2+a13B3+a14*B4...,

More generally stated as

Y＝AB+n

Where a is a coupling matrix whose diagonal elements are self-coupling coefficients, which tend to be much larger than the off-diagonal elements. B is the main beam vector, n is other interference and noise contributions, and Y is the actual output. Interference from other directions, including interference from other sources, can be reduced by an optimization algorithm.

The optimization algorithm may be a variety of algorithms, such as Least Mean Square Error (LMSE) and zero forcing (force zero), and in the case of a known coupling matrix A, taking

B＝(A ^H A) ^-1 AHY

In the case of an unknown coupling matrix a, an iterative approach to a may also be employed.

The multi-beam tracking and interferer cancellation unit 412 combines the signal and the interferer source main beam using an optimization algorithm and suppresses the signals from the alien source main beam 123 and the interferer source main beam 121.

The control unit 416 in the digital signal processing unit 205 forms an operation clock by a frequency synthesizer or other clock based on an external clock signal, generates control timing, and various control signals as needed to perform beat control.

The multi-beam controller 404 in the digital signal processing unit 205 updates the number and pointing direction of the plurality of desired signal sources 101/102 and the plurality of interference sources 103/104, and various receiving parameters in real time according to the working beat through the digital control signal interface 206. As previously described, multi-beam controller 404 may be in a centralized mode as shown in fig. 4, or may be designed to be partially distributed in a centralized manner, i.e., one part remains in fig. 4 and another part is distributed into sub-modules in an array; or may be entirely distributed, such as integrated in analog multi-beam receiving unit 202. The digital control signal interface 206 is partially adjusted or divided into blocks according to the implementation of the multi-beam controller 404, and is also partially distributed.

The control unit 416 of the dsp 205 also has a special control function, which can dynamically adjust the segmentation threshold 611 according to the receiving status. When the division threshold 611 is selected to be low, the number of main beams appearing is large, and the amount of calculation in the following is also large. When the division threshold 611 is selected to be high, the number of main beams appearing is small, and the amount of calculation in the following is also small. The control unit 416 is responsible for controlling the number of main beams, increasing or decreasing the complexity of the optimization algorithm, and dynamically balancing the received signal quality with the required minimum power consumption.

When K is greater than the number of primary beams, a portion of the beams may be extracted to serve as secondary beams. There are two types of auxiliary beams: an auxiliary search beam and an auxiliary tracking beam. The auxiliary search beam is used for randomly searching in a two-dimensional space, searching and finding a new emission source; the auxiliary tracking beam detects whether there is a preferred main beam position direction in the main beam tracking area 510 defined as the main beam, so as to update in real time or in the next working cycle. A schematic diagram of the tracking of the position of the main beam by the auxiliary beam is shown in fig. 7, and possible implementations are (a), (b), (c), (d), etc. That is, the position of the main beam may be tracked by one auxiliary tracking beam, such as (a), or the position of the main beam may be tracked by a plurality of auxiliary tracking beams, such as (b), (c), (d), etc., or may be time-shared.

A schematic flow chart of a process for receiving coupling of a required source and an interference source by using a receiving method of a two-dimensional analog multi-beam receiving array is shown in fig. 8.

The technology proposed in the invention can be applied to occasions such as wireless communication, mobile communication, satellite communication and the like. Because the radar technology and the communication technology are many common points, the technology can also find an application scene in the radar field for realizing multi-target tracking and real-time interference elimination.
