Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority to 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 relates to the technical field of communications, and in particular to encoding methods, devices and readable storage media. [Background technology]

[0003] A full-rate orthogonal codebook can simultaneously obtain full diversity gain and full rate, but in such codebooks, up until now, full-rate orthogonal codebooks for complex numbers only exist with dimension N=2, and full-rate codebooks for real numbers only exist with dimensions N=2, 4, 8. A full-rate pseudo-orthogonal codebook extends the dimension of a full-rate orthogonal codebook, and especially in a complex number field, such a codebook can obtain a diversity gain slightly inferior to the full diversity gain while being extended to a dimension of N≧2. However, such a codebook has a problem that the orthogonality of the codebook is lost, and thus the maximum likelihood detection by simple linear processing cannot be performed at the receiving end, and the processing complexity at the receiving end increases, resulting in a deterioration in communication performance.

[0004] A non-full-rate orthogonal codebook ensures the orthogonality of the codebook by reducing the bandwidth utilization rate or rate requirement, but 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.

[0021] In order to better understand the technical solution of the present application, the following will be first described.

[0022] Future 6G communication networks will need to support massive IoE, where the number of IoT devices will reach 100 billion levels, and the connection density will be 10-100 times higher than that of 5G, reaching 10-100 devices / m 2 The huge number of IoT devices will bring new challenges in terms of cost and power consumption. Passive devices with cellular networking, low cost, low power consumption, and even zero power consumption will be the trend for the development of future IoT devices. Conventional passive terminals are limited by their power consumption and hardware functions, and their communication transmission distance is mostly less than 10m, which is far from the cellular coverage goal of 100m. Therefore, the effective improvement of the communication distance of passive terminals has become a difficult problem to be solved after the technology is cellular networked.

[0024] Full-rate Orthogonal Space-Time Block Code (OSTBC) Space-time block code (STBC) is widely applied in cellular communication 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 the 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 space-time block coding codewords, which optimize the codebook of the traditional Alamouti code to reduce the complexity of hardware implementation and the high detection error rate.

[0046] A full-rate orthogonal codebook can obtain full diversity gain and full rate at the same time, but until now, only full-rate orthogonal codebooks for complex numbers have dimension N=2, and only full-rate codebooks for real numbers have dimension N=2, 4, 8. A full-rate pseudo-orthogonal codebook extends the dimension of a full-rate orthogonal codebook, and in particular, in a complex number field, such a codebook can be extended to a dimension of N≧2, while obtaining a diversity gain slightly inferior to the full diversity gain. However, such a codebook has a problem that the orthogonality of the codebook is lost, and the maximum likelihood detection by simple linear processing is not possible at the receiving end, and the processing complexity at the receiving end increases, and the communication performance is also deteriorated. A non-full-rate orthogonal codebook ensures the orthogonality of the codebook by reducing the bandwidth utilization rate or the rate requirement, but all of the conventional non-full-rate orthogonal codebooks are designed for conventional active high frequency communication, and do not take into account the modulation characteristics and implementation complexity of passive terminals such as backscatter communication. 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 for the dimension N=2.

[0047] Since backscattering communication controls the width or phase of the signal by changing the load impedance, there will be some errors in the width or phase of the output signal, considering that other elements of the modulation circuit of the backscattering communication are non-ideal. However, if these signal errors are within a recognizable range, there will be no effect on the demodulation of the signal. Therefore, the smaller the load impedance to be changed in each antenna, the larger the allowable 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 problem of the complexity of implementing 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 implementation complexity of the modulation.

[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 FIG. 2, an embodiment of the present application provides an encoding method, in which an executing subject is an encoding end, and the encoding end may be a terminal device or a network side device. The method includes: The method includes step 201 in which an encoding end performs space-time block coding on data based on a preset codebook.

[0051] In the embodiment of the present application, the preset codebook is a non-full-rate complex field orthogonal codebook, which replaces the Alamouti codebook sub-blocks in the codebook with new space-time block code NSTBC codebook sub-blocks, and each column of the preset codebook is orthogonal to each other.

[0052] It should be noted that the step of encoding the data with a space-time block code may involve encoding source data waiting to be transmitted.

[0053] In the embodiment of the present application, by replacing the Alamouti codebook sub-blocks in the orthogonal codebook of a non-full-rate complex field with NSTBC codebook sub-blocks, the rate requirement is reduced based on the orthogonal codebook of a non-full-rate complex field, thereby ensuring the orthogonality of the codebook, reducing the processing complexity of the receiving end, and avoiding the deterioration of communication performance; on the other hand, the number or types of load impedances of some antennas can be reduced while ensuring 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 of a non-full-rate complex field with low implementation complexity is designed. The codebook structure is redesigned based on the conventional orthogonal codebook of a non-full-rate complex field, ensuring that each column of the designed codebook is orthogonal to each other, while reducing the impedance matching types corresponding to some antennas, thereby reducing the implementation complexity of the system and effectively reducing the detection error rate.

[0056] The characteristics of a non-full-rate orthogonal codebook for a complex number field having the structure of the present application will now be described.
