Detailed Description
In order to understand the technical scheme of the application more clearly, the radio frequency chip and related technical contents are described first.
The Radio Frequency is abbreviated as RF, which is Radio Frequency current, is a high-Frequency alternating current variable electromagnetic wave, is an abbreviation of Radio Frequency, and represents electromagnetic Frequency which can radiate into space, and the Frequency range is 300 KHz-300 GHz. Alternating current that varies less than 1000 times per second is referred to as low frequency current, and alternating current that varies more than 10000 times is referred to as high frequency current, and radio frequency is such a high frequency current. High frequency (greater than 10K); the radio frequency (300K-300G) is the higher frequency band of the high frequency; the microwave band (300M-300G) is in turn the higher band of radio frequencies.
The radio frequency chip is an electronic component which converts radio signal communication into a certain radio signal waveform and sends out the radio signal waveform through antenna resonance, and comprises a power amplifier, a low noise amplifier and an antenna switch. The radio frequency chip architecture comprises two major parts, namely a receiving channel and a transmitting channel, as shown in fig. 1.
Wireless communication is to transmit information after encoding by one symbol by changing parameters such as amplitude, phase, and frequency of electromagnetic waves in the physical world. In brief, the following symbols may be used to represent the communication signals:
the technical scheme in the application is further described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the application discloses a signal processing method, which comprises the following steps:
s101, responding to the obtained pre-emission signal, and obtaining the occupation condition of a channel in a radio frequency chip;
s102, selecting or newly creating two channels in a non-occupied state and dividing a pre-emission signal into a high frequency band and a low frequency band according to channel frequencies; and
s103, respectively transmitting the high frequency band and the low frequency band by using two channels in a non-occupied state;
wherein, the newly-built channels in the unoccupied state can be positioned on two adjacent isolation areas;
the high frequency band and the low frequency band are alternately arranged in the sequence.
The signal processing method disclosed by the application is applied to the transmission application scene of the radio frequency chip, when a plurality of wireless terminals need to simultaneously use one radio frequency chip to transmit signals, a transmission scheme needs to be selected according to the use condition of a channel in the radio frequency chip, and related technologies need to be introduced.
A channel, also called a channel or frequency band, is a data signal transmission channel with a wireless signal as a transmission carrier. Radio communication uses electromagnetic waves, and the frequency of the electromagnetic waves is divided into different "segments", i.e. frequency bands, which refer to a frequency range of continuous electromagnetic waves.
Referring to fig. 2, for the frequency band, channels are further divided to avoid competition among a plurality of devices. Since the more channels, the narrower the width of each channel, the greater the probability of collision for terminals within the channel, and if collision is to be avoided or reduced, more time is required to monitor for collisions and, in the event of problems, the data packets need to be retransmitted.
The difference between the maximum and minimum frequencies in a channel, called the channel bandwidth, represents the size of the frequency range covered by the channel. Factors influencing the transmission rate are mainly channel bandwidth and frequency, and the larger the bandwidth is, the larger the transmission rate is; the higher the frequency, the higher the transmission rate.
From the above, it can be known that the data transmission speed of a channel is fixed, and for an existing radio frequency chip (frequency is fixed), the resource amount (number multiplied by width) of the channel is also fixed, and when the data transmission speed of a channel cannot meet the use requirement, the channel or the data to be transmitted needs to be optimized, so that the data can be sent out within the required time.
The signal processing method disclosed by the application is applied to a logic control unit in a radio control radio frequency chip, the radio frequency chip is applied to the field of radio control, a control signal is converted into a radio signal in the uplink direction, and a received radio signal is converted into a control signal in the downlink direction.
The radio control process has higher requirements on the signal sending speed, because the signal delay is directly influenced, and meanwhile, in application scenes such as complex actions, complex postures, multi-object control and the like, the number of signals is also large, and the data interaction between a plurality of sensors and a plurality of control chips is involved in the middle.
In step S101, a logic control unit in the radio frequency chip receives a pre-transmit signal, and in response to the received pre-transmit signal, the logic control unit obtains an occupation condition of a channel in the radio frequency chip, matches the pre-transmit signal with a usable channel after obtaining the occupation condition of the channel, and at this time, two situations will occur, that is, using one channel to meet a transmission requirement of the pre-transmit signal and using multiple channels to meet a transmission requirement of the pre-transmit signal, respectively.
When a channel can meet the transmission requirement of the pre-transmission signal, the channel is directly used for transmitting the pre-transmission signal; when it is necessary to satisfy the transmission requirement of the pre-transmission signal using a plurality of channels, the process advances to step S102.
In step S102, two channels in a non-occupied state are selected or newly created, and the pre-transmission signal is divided into a high frequency band and a low frequency band according to the channel frequency, as shown in fig. 3, and then the high frequency band and the low frequency band are transmitted by using the two channels in a non-occupied state, that is, the content in step S103.
The two channels may be generated by selecting both channels or by using a new mode, or by selecting both channels and creating the channels simultaneously, and of course, the level of the selected mode is higher than that of the new mode, that is, only when the number of channels obtained by the selected mode is smaller than two, the new channel is created by using the new mode, and the new channel in the unoccupied state may be located in two adjacent isolation areas.
For the relationship between the high frequency band and the low frequency band, the high frequency band and the low frequency band are alternately arranged in a sequential order. That is, for a pre-transmitted signal, it is divided into a plurality of segments, with a low frequency band between any two high frequency bands and a high frequency band between any two low frequency bands.
In the signal processing method provided by the application, the method for segmenting the pre-transmission signal and respectively transmitting the pre-transmission signal by using different channels is used, so that the bandwidth can be more fully utilized. Meanwhile, when the bandwidth is insufficient, the pre-transmission signals can be sent out by using narrower channels and different channel sending modes after being divided.
This approach can alleviate the congestion caused by insufficient channel resources to some extent, and also occupies as little frequency resources as possible, because the processing schemes of modulating signals at high and low frequencies are used in the present application. Taking a specific modulation signal as an example, adding a modulation carrier signal to the modulation signal to obtain a modulated signal, wherein the shape of the modulated signal is matched with that of the modulation signal.
The modulated signal is divided into a high frequency band, which is modulated with a high frequency modulated carrier signal, and a low frequency band, which is modulated with a low frequency modulated carrier signal. The high frequency modulated carrier signal and the low frequency modulated carrier signal are both a fixed frequency.
It will be appreciated that a modulated carrier signal at a high frequency has a higher profiling effect, which may result in a higher degree of conformity of the shape of the modulated signal to the shape of the modulated signal. For the low frequency band, too dense modulation carriers can result in increased congestion of the waveforms herein and are more susceptible to interference, as the overly congested waveforms, after being interfered, can increase in demodulation (recovery) difficulty and corresponding demodulation time.
The width adjustment of the isolation region according to the interference degree comprises the following steps:
s201, determining the frequency of a channel in a non-occupied state;
s202, determining a dividing line of the pre-transmitted signal; and
s203, adjusting the height of the dividing line according to the frequency of the channel in the unoccupied state and dividing the pre-emission signal into a high frequency band and a low frequency band after the height is determined.
Specifically, in steps S201 to S203, the frequency-to-pre-transmit signal dividing ratio is determined according to the channel width, so that the channel resources can be more fully utilized.
It will be appreciated that the signal is modulated before it can be transmitted through the antenna. Electromagnetic waves have three characteristics, namely amplitude, frequency and phase. Taking amplitude as an example, the amplitude modulation technology is to multiply an information source signal and a modulation carrier signal and then mix the information source signal and the modulation carrier signal together so as to obtain a new modulation signal, the amplitude value of the modulation signal fluctuates up and down along with the amplitude value of the information source signal, the frequency of the modulated signal is changed into the almost same shape as the root modulation carrier signal, and the change trend of the amplitude value of the signal is kept consistent with the change trend of the information source signal.
The dividing line of the pre-transmitting signal is determined while the frequency of the channel to be used is obtained, then the height of the dividing line is adjusted according to the frequency of the channel in the unoccupied state, and the pre-transmitting signal is divided into a high frequency band and a low frequency band after the height is determined.
The specific process is that firstly, two frequencies, namely a first frequency and a second frequency, are determined, wherein the first frequency is larger than the second frequency, the first frequency is used for modulating a high frequency band, and the second frequency is used for modulating a low frequency band.
Referring to fig. 3, a division line is constructed in a manner that a plurality of intersections exist between the division line and the pre-emission signal in the X-axis direction, the pre-emission signal between any two adjacent intersections is a high frequency band or a low frequency band, specifically, the pre-emission signal is located below a horizontal line and the pre-emission signal is located above the horizontal line.
The process of adjusting the height of the dividing line according to the frequency mainly comprises the steps of determining the length of the low frequency band, and mainly comprising two references of a transverse dimension (shown in fig. 4) and a longitudinal dimension (shown in fig. 5), wherein the height of the dividing line is determined when the transverse dimension or the longitudinal dimension reaches a set value.
In some examples, referring to fig. 6, each of the channels in the unoccupied state includes a use region for the modulated signal and two isolation regions of equal width, the isolation regions acting to reduce interference between adjacent channels. The use of an area between two isolation areas, i.e. the use of isolation areas on both sides of the use area, reduces the interference between adjacent channels.
It will be appreciated that electromagnetic waves propagate in channels subject to interference from electromagnetic waves propagating in adjacent channels, and therefore an isolation region is required to reduce interference, and the closer the frequencies of the two electromagnetic waves are, the more likely interference will occur. The isolation region has the function of increasing the frequency difference of the two electromagnetic waves so as to achieve the purpose of reducing interference.
For the width of the isolation region, the application is also adjusted in the following way:
s301, determining the interference degree between a high frequency band or a low frequency band in a use area and an adjacent channel; and
s302, adjusting the width of the isolation area according to the interference degree;
wherein the width of the isolation region is positively correlated with the degree of interference.
Specifically, the width of the isolation region is adjusted according to the interference degree between the high frequency band or the low frequency band in the usage region and the adjacent channel. It will be appreciated that the degree of interference is related to both the width of the isolation region and the signal in the adjacent channel, and thus the width of the isolation region can be adjusted by calculating the degree of interference, as the isolation region can also be considered a channel, except that the channel is in an unused state.
It will be further understood that the use area and the isolation area in the channel can be regarded as lanes, and the electromagnetic waves can be regarded as vehicles running on the lanes, and when two vehicles run on two adjacent lanes at the same time, the probability of occurrence of an accident is high, so that it is necessary to add the isolation area between the two lanes, and the wider the isolation area, the lower the probability of occurrence of an accident. However, the width of the isolation area needs to be limited because the greater the width of the isolation area, the more the number and width of lanes will be compressed.
The width of the isolation region is adjusted according to the interference degree as follows:
calculating the nearest distance (S shown in figure 7) and the included angle (shown in figure 8) between the signal segment in the frequency domain and the signal on the adjacent channel, wherein the signal segment comprises a high frequency band and a low frequency band; and carrying out weighted calculation on the nearest distance and the included angle to obtain an influence parameter, and adjusting the width of the isolation region according to the influence parameter.
The two parameters influencing the interference degree are the shortest distance and the included angle respectively, wherein the shortest distance represents the distance between two electromagnetic waves in space, and the farther the distance is, the smaller the interference degree is; the included angle represents the overlap ratio of two electromagnetic waves in space, and the lower the overlap ratio is, the smaller the interference ratio is.
For calculating the nearest distance and the included angle, the application uses a weighted calculation mode to set two weighted proportions, namely a first proportion and a second proportion, and the calculation formula of influencing parameters is as follows:
influence parameter = nearest distance x first proportion + included angle x second proportion;
the method for adjusting the width of the isolation region according to the influence parameter is that after the influence parameter is obtained, the influence parameter is compared with a set influence parameter reference value, and if the influence parameter is greater than or equal to the influence parameter reference value, the width of the isolation region does not need to be adjusted; if the influence parameter is smaller than the influence parameter reference value, the width of the isolation area is increased and the influence parameter is recalculated until the influence parameter is larger than or equal to the influence parameter reference value.
Of course, when the processing method cannot satisfy the determination condition that the influence parameter is equal to or greater than the influence parameter reference value, the method of increasing the included angle may be selected to satisfy.
In some examples, the isolation region width adjustment splitting scheme further includes adjusting the channel frequency and shifting the phase of the high frequency band and/or the low frequency band. Adjusting the channel frequency and shifting the phase of the high and/or low frequency bands can increase the closest distance.
In some examples, the method further comprises amplitude adjustment of the low frequency band, wherein the amplitude adjustment is used for the low frequency band by adding a fixed value to the amplitude of any part of the low frequency band (taking a coordinate system as a reference, moving up or down in the y-axis direction), and the method can also increase the nearest distance.
The application also provides a signal processing device, which comprises:
the acquisition unit is used for responding to the acquired pre-emission signal and acquiring the occupation condition of the channel in the radio frequency chip;
the first processing unit is used for selecting or newly creating two channels in a non-occupied state and dividing the pre-transmitted signal into a high frequency band and a low frequency band according to the channel frequency; and

wherein, the newly-built channels in the unoccupied state can be positioned on two adjacent isolation areas;

and the second processing unit is used for adjusting the height of the dividing line according to the frequency of the channel in the unoccupied state and dividing the pre-transmitted signal into a high frequency band and a low frequency band after the height is determined.

Further, the method also comprises amplitude adjustment of the low frequency band, wherein the amplitude adjustment comprises that the amplitude of any part of the low frequency band is increased or reduced by a fixed value.
