Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority from Chinese Patent Application No. 202210067513.9 filed in China on January 20, 2022, the entire contents of which are incorporated herein by reference.

[0002] The present application is in the field of communications, and specifically relates to encoding methods, devices and readable storage media. [Background technology]

[0003] A full-rate orthogonal codebook can simultaneously achieve full diversity gain and full rate. However, until now, full-rate orthogonal codebooks for complex fields have only existed for dimension N=2, and full-rate codebooks for real fields have only existed for dimension N=2, 4, and 8. A full-rate pseudo-orthogonal codebook extends the dimension of full-rate orthogonal codebooks. In particular, in complex fields, such codebooks can be extended to dimensions N≧2, while still achieving a diversity gain slightly inferior to full diversity gain. However, such codebooks have a problem in that the orthogonality of the codebook is lost, making it impossible to perform maximum likelihood detection using simple linear processing at the receiving end. This increases the processing complexity at the receiving end and degrades communication performance.

[0004] Non-full-rate orthogonal codebooks ensure the orthogonality of the codebook by reducing the bandwidth utilization rate or rate requirement. However, conventional non-full-rate orthogonal codebooks are all designed for conventional active high-frequency communications, and do not take into account the modulation characteristics and implementation complexity of passive terminals such as backscatter communications.

Passive devices, which offer cellular networking, low cost, low power consumption, and even zero power consumption, will be the trend in the future development of IoT devices. Conventional passive devices are limited by their power consumption and hardware capabilities, and their communication transmission distances are usually less than 10 meters, far from the 100-meter coverage goal of cellular networks. Therefore, effectively improving the communication distance of passive devices has become a difficult problem to be solved after the technology is adopted into cellular networks.

[0024] Full-rate Orthogonal Space-Time Block Code (OSTBC) Space-time block code (STBC) is widely applied in cellular communications and wireless local area networks. STBC introduces signal redundancy in the space and time domains and performs block coding on the transmission matrix with a rational structure to obtain diversity gain and antenna gain without increasing bandwidth.

[0038] Novel Space-Time Block Coded (NSTBC) In recent years, with the deepening of research on backscatter communication, some scholars have proposed the concept of backscatter diversity and designed the corresponding codewords for space-time block coding, which reduce the hardware implementation complexity and the high detection error rate by optimizing the codebook of the traditional Alamouti code.

[0046] A full-rate orthogonal codebook can achieve both full diversity gain and full rate. However, until now, full-rate orthogonal codebooks for complex fields only exist with dimension N=2, and full-rate codebooks for real fields only exist with dimension N=2, 4, and 8. Full-rate pseudo-orthogonal codebooks extend the dimension of full-rate orthogonal codebooks. In particular, in complex fields, such codebooks can be extended to dimensions N≧2, while achieving a diversity gain slightly inferior to full diversity gain. However, such codebooks lose their orthogonality, making maximum likelihood detection using simple linear processing impossible at the receiving end, increasing the processing complexity at the receiving end and degrading communication performance. Non-full-rate orthogonal codebooks ensure codebook orthogonality by reducing bandwidth utilization or rate requirements. However, conventional non-full-rate orthogonal codebooks were designed for conventional active high-frequency communications and did not take into account the modulation characteristics and implementation complexity of passive terminals such as backscatter communications. The new NSTBC codebook takes into account the modulation characteristics and implementation complexity of passive terminals such as backscattering communication, but the conventional NSTBC codebook exists only when the dimension N=2.

[0047] Since backscatter communication controls the signal width or phase by changing the load impedance, there will be some error in the output signal width or phase if other elements of the backscatter communication modulation circuit are non-ideal. However, as long as these signal errors are within a recognizable range, they will not affect signal demodulation. Therefore, the smaller the load impedance that needs to be changed at each antenna, the larger the tolerable error will be, and the smaller the false detection rate will be. None of the conventional full-rate orthogonal codebooks, full-rate pseudo-orthogonal codebooks, and non-full-rate orthogonal codebooks take into account the implementation complexity issues of these modulations.

[0048] Therefore, the technical solution of the present invention redesigns a non-full-rate orthogonal codebook with a codebook dimension N≧2 by combining a non-full-rate orthogonal codebook and an NSTBC codebook structure, thereby expanding the dimension of the orthogonal codebook and reducing the modulation implementation complexity.

[0049] Next, the encoding method provided by the embodiments of the present application will be described in detail based on the embodiments and their application scenarios with reference to the drawings.

[0050] Referring to Figure 2, an embodiment of the present application provides an encoding method, which is performed by an encoding end, and the encoding end may be a terminal device or a network side device.

[0052] The step of encoding data with a space-time block code may involve encoding source data waiting to be transmitted.

[0053] In the embodiments of the present application, the Alamouti codebook sub-blocks in the non-full-rate complex field orthogonal codebook are replaced with NSTBC codebook sub-blocks. By using the non-full-rate complex field orthogonal codebook, the rate requirement can be reduced to ensure the orthogonality of the codebook, reduce the processing complexity at the receiving end, and avoid deterioration of communication performance. Meanwhile, the number or types of load impedances of some antennas can be reduced to ensure diversity gain based on the NSTBC codebook, thereby effectively reducing the detection error rate.

[0054] Optionally, the preset codebook may be referred to as a non-full-rate complex field orthogonal codebook.

[0055] In the embodiment of the present application, an orthogonal codebook for a non-full-rate complex number field with low implementation complexity is designed. The codebook structure is redesigned based on the conventional orthogonal codebook for a non-full-rate complex number field, ensuring that each column of the designed codebook is orthogonal to each other, while reducing the number of impedance matching types corresponding to some antennas, thereby reducing the implementation complexity of the system and effectively reducing the detection error rate.
