The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1A is a flowchart of an information transmission method according to an embodiment of the present invention, where this embodiment is applicable to how communication devices transmit bitstream information when transmitting the bitstream information between the communication devices, and the method may be executed by an information transmission apparatus according to a third embodiment of the present invention, where the apparatus may be implemented by software and/or hardware and is integrated in a first communication device, and the method specifically includes the following steps:

s110, bit stream information to be transmitted is obtained, and the bit stream information is segmented according to a preset segmentation bit value so as to obtain a current bit paragraph.

Bit stream (BitTorrent), a content distribution protocol, transmits information through software distribution systems and point-to-point technologies; information to be transmitted based on a bit stream is a binary bit sequence and has a characteristic of a large volume (i.e., contains long bits), and therefore, it is necessary to perform segmentation processing and segmentation transmission on bit stream information to ensure reliability of information transmission and avoid information loss in transmission, as shown in fig. 1B, bit segmentation is performed on the bit stream, and each bit segment can be represented as a _i ＝(a _i,0 ，a _i,1 ,…a _i,N-1 ) 1, 2 … N, where i represents a sequence number of a bit segment, N represents a number of bits of the bit segment, and N is the number of bit segments included in the current bit stream to be transmitted, and is equal to the number of bits of the bit stream information to be transmitted divided by the number of bits of each bit segment; after segmenting the bit stream information, taking each bit segment as a spread spectrum modulation unit and respectively transmitting the bit segments, wherein the bit segments are equal in length and are all preset segmentation bit values; the preset segmentation bit value is a segmentation bit value set when the bitstream information to be transmitted is subjected to segment division, for example, 20 bits, that is, the bitstream information to be transmitted is subjected to segment division once every 20 bits, and a plurality of bit segments with 20 bits are obtained. In particular, the predetermined segment bit value may be based onSetting the number of bits of the bitstream information to be transmitted to ensure that the length of the bitstream information to be transmitted is an integral multiple of the preset segmented bit value, and further ensuring that the number of bits of each bit paragraph is the same.

And S120, according to a preset frequency point bit value, a preset spread spectrum bit value and a preset modulation bit value, grouping and configuring the current bit section to obtain a frequency point bit group, a spread spectrum bit group and a modulation bit group of the current bit section.

Different transmission channels have different numbers of bits of information to be transmitted and different transmission efficiencies, so that before configuring each bit segment in a grouping manner, channel estimation needs to be performed on the current transmission channel to determine the channel quality; as shown in fig. 1B, determining a preset frequency point bit value O, a preset spread spectrum bit value M, and a preset modulation bit value L according to the channel quality estimation result, so that the grouping configuration of the current bit segment is adapted to the current wireless transmission channel; wherein, the bit number N of the bit segment is O + M + L, and L is a power exponent of 2. The preset frequency point bit value refers to the length of bit stream information used for representing frequency point information; the preset spread spectrum bit value is the length of the bit stream information used for acquiring the spread spectrum code sequence; the preset modulation bit value refers to the length of bit stream information for performing spread spectrum modulation; it is noted that the sum of the preset frequency point bit value, the preset spread spectrum bit value and the preset modulation bit value should be equal to the preset segmented bit value, and the preset modulation bit value should be a power exponent of 2, so as to select a corresponding symbol modulation mode for the modulation bit group.

The frequency point bit group is used for acquiring frequency information transmitted by a current bit segment, the spread spectrum bit group is used for acquiring a spread spectrum code sequence corresponding to a current modulation bit group, and the modulation bit group is used for acquiring a spread spectrum signal to be transmitted. In the embodiment of the invention, partial information of the bit stream to be transmitted is hidden in the frequency point information and the spread spectrum code sequence, so that time-frequency resources required for wireless transmission of the current bit segment are reduced, and the utilization rate of the time-frequency resources in wireless communication is improved.

According to the preset frequency point bit value, the preset spread spectrum bit value and the preset modulation bit value, the current bit segment is subjected toGrouping configuration is carried out, namely, the current bit paragraph is correspondingly divided into three parts, namely a frequency point bit group, a spread spectrum bit group and a modulation bit group of the bit paragraph; as shown in fig. 1B, after grouping the bit segments according to the preset frequency point bit value O, the preset spread spectrum bit value M and the preset modulation bit value L, the frequency point bit group can be represented as a frequency point bit group

The spread bit group can be represented as

The modulation bit group can be expressed as

Namely, it is

Through the process, grouping of the bit stream information to be transmitted is realized.

S130, acquiring a matched first target spreading code sequence from a spreading code sequence set according to the spreading bit group of the current bit paragraph; wherein the set of spreading code sequences comprises at least one spreading code sequence.

A spreading code sequence, which is a coefficient when spreading modulation is performed on the modulation bit group of the current bit segment, and has a characteristic of approximating a random signal, so that the spreading code sequence can be used as a spreading parameter when spreading modulation is performed; a spreading code sequence including a longest linear feedback shift register sequence, a Gold code sequence, a Hadamard (Hadamard) sequence, and a Discrete Fourier Transform (DFT) basis vector of variation; the longest linear feedback shift register sequence is a periodic pseudorandom sequence which is easy to realize, has the advantage of strong regularity, and is widely applied to wireless communication; the Gold code sequence is a pseudo-random sequence provided on the basis of a longest linear feedback shift register sequence, and has good autocorrelation and cross-correlation properties; the Hadamard sequence is a sequence based on a Hadamard matrix, and any two lines of data in the Hadamard matrix are mutually orthogonal, so the Hadamard sequence has better cross-correlation property; the DFT change basis vectors are a series of basis vectors based on DFT change and have good cross correlation. The spread spectrum code sequence set is constructed in advance, the set formed by a plurality of spread spectrum code sequences is used as local storage information of each communication device, and the communication devices can acquire the spread spectrum code sequences required by modulation or demodulation through the locally stored spread spectrum code sequence set when carrying out spread spectrum modulation or demodulation; in the spreading code sequence set, each spreading code sequence has a corresponding serial number, so that each spreading code sequence is convenient to search. The first target spreading code sequence is the spreading code sequence corresponding to the spreading bit group in the current bit segment.

After acquiring the spread bit group of the current bit segment, as shown in fig. 1B, the binary spread bit group is used

Converting the decimal value into a decimal value, and taking the converted value as a mapping serial number for searching a matched spread spectrum code sequence; searching in the spread spectrum code sequence set according to the mapping sequence number; for example, if the spreading bit group is 0010 (four bits), and the corresponding converted decimal value is 2, the 2 nd spreading code sequence in the spreading code sequence set is taken as the target spreading code sequence; obtaining matched target spread code sequence C by performing numerical transformation on spread bit group _i The spread spectrum bit group information is hidden in the spread spectrum code sequence information for transmission, so that the utilization rate of time-frequency resources is improved; and because different bit segments adopt different spreading code sequences, the bit segments do not interfere with each other.

Optionally, in an embodiment of the present invention, the number of spreading code sequences in the spreading code sequence set is related to the preset spreading bit value, and the number of bits of the spreading code sequence is related to the preset modulation bit value. Specifically, the number of spreading code sequences in the spreading code sequence set needs to be greater than or equal to a value obtained by converting a preset spreading bit value, so as to ensure that a corresponding target spreading code sequence can be searched in the spreading code sequence set according to each preset spreading bit value; taking the preset spreading bit value of 4 as an example, the number of bits corresponding to the spreading bit group is 4, and when each bit value of the spreading bit group is 1, the converted decimal number is 15, and then there should be at least 16 spreading code sequences in the spreading code sequence set, so as to ensure that each spreading bit group can find the corresponding spreading code sequence. The number of bits of the spreading code sequence in the spreading code sequence set can be consistent with the preset modulation bit value, so that the spreading modulation of the modulation bit group is realized according to the target spreading code sequence; when the modulation bit group is subjected to spread spectrum modulation, selecting part of the bits (such as the front part, the rear part or the middle part) of the spread spectrum code sequence to perform spread spectrum modulation on the modulation bit group, and ensuring that the bits of the adopted part of the spread spectrum code sequence are consistent with the bits of the modulation bit group; for example, the preset modulation bit value is 10, that is, the number of bits corresponding to the modulation bit group is 10, and the length of the corresponding spreading code sequence should be greater than or equal to 10.

In spread spectrum communications, prior to spread spectrum modulation, groups of modulation bits are modulated as shown in FIG. 1B

Firstly, information modulation is needed to form corresponding modulation symbols S _i (ii) a Then, the digital signal after information modulation is spread spectrum modulated by adopting a first target spread spectrum code sequence to obtain a corresponding spread spectrum signal t _i The frequency spectrum of the digital signal is widened, so that the same frequency spectrum resource can be maximally shared by multiple bit sections.

Frequency point spacing coefficient, meansThe preset unit frequency variation interval can be set according to the requirement, specifically, according to the formula f _i ＝F _i ·Δf+f ₀ Acquiring a transmission frequency point, wherein f _i For transmission frequency points, i is the number of the transmission frequency point, F _i Is decimal number after frequency point bit group conversion, delta f is frequency point interval coefficient, f ₀ A bandwidth starting frequency for the communication channel; the frequency point interval coefficient has the function of ensuring that the acquired transmission frequency point is located in a communication channel, and avoiding that the acquired transmission frequency point exceeds the bandwidth range of the communication channel, for example, the decimal number after the frequency point bit group conversion is 256, the bandwidth of the communication channel is 128Hz, and obviously, when Δ f is large (for example, 1Hz), the acquired transmission frequency point is located outside the communication channel, and effective transmission of information cannot be realized, so the frequency point interval coefficient is related to the bandwidth of the communication channel and/or a preset frequency point bit value. Specifically, Δ f needs to be less than or equal to the bandwidth of the communication channel/the decimal number corresponding to the preset frequency point bit value, for example, when the bandwidth of the communication channel is 127Hz, the preset frequency point bit value is 7, that is, the frequency point bit group is a 7-bit number, the corresponding decimal number is 127, and Δ f needs to be less than or equal to 1Hz, so that the finally obtained transmission frequency point is, in the communication channel (that is, from the minimum frequency to the maximum frequency), greater than or equal to the minimum frequency of the communication channel, and less than or equal to the maximum frequency of the communication channel. As shown in fig. 1B, by using a part of the information of the current bit segment, i.e. the frequency point bit group

Mapping to a transmission frequency point f _i The time frequency resource required by transmitting the current bit paragraph can be reduced, and the utilization rate of the time frequency resource is improved.

In the embodiment of the invention, the modulation mode corresponding to the current modulation bit group is determined according to the modulation order; specifically, a symbol modulation mode corresponding to each modulation order is agreed in advance between a first communication device (transmitter) and a second communication device (receiver), that is, for each modulation order, the first communication device performs information modulation by adopting an agreed symbol modulation mode, and the second communication device performs information demodulation by adopting a symbol demodulation mode corresponding to the agreed symbol modulation mode; the predetermined symbol modulation scheme may be any one of symbol modulation schemes corresponding to the modulation orders, for example, when the modulation order is 2, each symbol of the code pattern represents two bits, and the predetermined symbol modulation scheme may be one of Binary Phase Shift Keying (BPSK) and differential coherent Binary Phase Shift Keying (DBPSK); when the modulation order is 4, the predetermined symbol modulation scheme may be one of Quadrature Phase Shift Keying (QPSK) and offset-Quadrature Phase Shift Keying (OQPSK); when the Modulation order is 16, the predetermined symbol Modulation scheme may be one of 16Quadrature Amplitude Modulation (16 QAM) and 16Amplitude Phase Shift Keying (16 APSK). After the modulation order is determined, acquiring an agreed symbol modulation mode according to the current modulation order; the corresponding modulation signals are obtained by matching the modulation bit groups with different lengths with corresponding different symbol modulation modes, so that the length of the modulation bit group is ensuredThe selection and the mode of generating the modulation signal are more flexible and diversified.

After acquiring the spread spectrum signal, as shown in fig. 1B, the spread spectrum signal t is processed _i Carrying out radio frequency modulation, and moving the frequency spectrum of the spread spectrum signal to the corresponding transmission frequency point f _i To pass through the corresponding transmission frequency point f _i For the spread signal t of the current bit segment _i Carrying out transmission; the radio frequency modulation mode may include vector modulation (IQ-path modulation); vector modulation means that a spread spectrum signal is divided into two paths of signals, carrier modulation is respectively carried out, and the two paths of carriers are orthogonal to each other, so that the frequency spectrum utilization rate can be improved.

Optionally, in this embodiment of the present invention, after transmitting the spread spectrum signal of the current bit segment to the second communication device according to the transmission frequency point of the current bit segment, the method may further include: continuously acquiring a next bit paragraph, and performing grouping configuration on the next bit paragraph according to a preset frequency point bit value, a preset spread spectrum bit value and a preset modulation bit value to acquire a frequency point bit group, a spread spectrum bit group and a modulation bit group of the next bit paragraph; acquiring a matched second target spreading code sequence in the spreading code sequence set according to the spreading bit group of the next bit paragraph; acquiring a spread spectrum signal of the next bit paragraph according to the second target spread spectrum code sequence and the modulation bit group of the next bit paragraph, and acquiring a transmission frequency point of the next bit paragraph according to the frequency point bit group of the next bit paragraph, the bandwidth starting frequency of the communication channel and the frequency point interval coefficient; and transmitting the spread spectrum signal of the next bit section to second communication equipment according to the transmission frequency point of the next bit section.

Specifically, when performing spread spectrum modulation on the bit stream information of the current bit segment, continuously acquiring the next bit segment, and performing spread spectrum modulation on the next bit segment; the process of performing spread spectrum modulation on the next bit segment is completely consistent with that of the current bit segment, the next bit segment is grouped to further obtain a corresponding transmission frequency point, a second target spread spectrum code sequence and a spread spectrum signal of the next bit segment, and the next spread spectrum signal is transmitted according to the transmission frequency point of the next bit segment; and continuing the process until the spread spectrum modulation of all the bit stream information to be transmitted is completed, and simultaneously sending the spread spectrum modulation signals corresponding to all the bit sections to the second communication equipment.

According to the technical scheme disclosed by the embodiment of the invention, after bit stream information to be transmitted is obtained, a frequency point bit group, a spread spectrum bit group and a modulation bit group of a current bit paragraph are obtained through bit paragraph division and grouping operation; simultaneously, acquiring a matched first target spread spectrum code sequence, a spread spectrum signal of the current bit paragraph and a transmission frequency point of the current bit paragraph according to the frequency point bit group, the spread spectrum bit group and the modulation bit group of the current bit paragraph; and finally, transmitting the spread spectrum signal of the current bit section to second communication equipment according to the transmission frequency point of the current bit section, and realizing the implicit transmission of part of information to be transmitted by setting a frequency point bit group and a spread spectrum bit group, thereby reducing the transmission data volume, improving the transmission efficiency and further improving the utilization rate of time-frequency resources.

And the transmission frequency point is a corresponding frequency point for receiving the spread spectrum signal transmitted by the first communication device in all the alternative frequency points. Specifically, after determining the alternative frequency points, as shown in fig. 2B, the second communication device performs processing on the received signals at all the alternative frequency points f ₁ ，…，f _k IQ demodulation to obtain corresponding spread spectrum signal

Wherein k is the number of the alternative frequency points; through the determination of the transmission frequency point, the decimal value corresponding to the frequency point bit group can be obtained, and then the matched binary frequency point bit group is obtained, so that the receiving and the recovery of the frequency point bit group information are realized.

Optionally, in the embodiment of the present invention, the alternative frequency point may be set by taking a frequency point interval coefficient every other frequency point as an alternative frequency point on the basis of the bandwidth starting frequency of the communication channel; the maximum value of the alternative frequency points is determined by the bandwidth starting frequency of the communication channel, the frequency point interval coefficient and the preset frequency point bit value; the alternative frequency point comprises the bandwidth starting frequency of the communication channel. For example, the bandwidth start frequency of the current communication channel is 870MHz, the frequency point interval coefficient is 1MHz, the preset frequency point bit value is 2, that is, the length of the frequency point bit group is 2, and when each frequency point bit is 1, the maximum decimal value after corresponding conversion is 3, then the corresponding acquired alternative frequency points are 870MHz, 871MHz, 872MHz, and 873 MHz.

Where j is the sequence number of the spreading code sequence, 2 ^M The number of the spread spectrum code sequences in the spread spectrum code sequence set is M, and M is a preset spread spectrum bit value; meanwhile, all the inner product operation values are sorted according to the magnitude of the modulus value through the comparison module so as to determine a target inner product value with the maximum modulus value, and a spreading code sequence corresponding to the target inner product value is a spreading code sequence corresponding to the current spreading signal, so that the acquisition of the spreading sequence matched with the current spreading signal is realized.
