Problems solved by technology

[0004] In the above-mentioned prior art solution, the encoding coefficients of each data block need to be transmitted between the encoding device and the decoding device, so that the decoding device can use these coefficients to restore a full-rank matrix, and then solve it, so that when the number of data blocks is very large When is large, the traffic that needs to transmit coding coefficients will be very large, so the existing technology scheme affects the efficiency of codec

Embodiment Construction

[0021] The embodiment of the present invention provides a coding and decoding method, communication system and equipment, which are used to improve the efficiency of coding and decoding.

[0022] The embodiment of the present invention can be applied to data transmission in a data network, and encodes and decodes the transmitted data. The specific data network is not limited. In the following embodiments, a network based on MIMO is used as an example for illustration.

[0023] In the encoding and decoding process of the embodiment of the present invention, the encoding device can calculate the encoding coefficients of other data blocks according to the first encoding coefficient of the initial data block and the preset encoding and decoding rules, so the encoding coefficients sent by the encoding device to the decoding device The encoded data block may not necessarily contain the encoding coefficients of all the data blocks, and the decoding device may also calculate the encodi...

Abstract

The invention discloses a coding and decoding method, a communication system and an apparatus for improving the efficiency of the coding and decoding. The method comprises: acquiring the data deblock to be transmitted, wherein the data deblock to be transmitted is composed of an initial data deblock and a second data deblock; acquiring a first coding coefficient of the initial data deblock; computing a second coding coefficient of the second data deblock based on the first coding coefficient and the preset coding and decoding regulation; coding the data deblock to be transmitted based on the first coding coefficient and the second first coding coefficient and acquiring the coding data block; transmitting the coding data block. The invention also provides a communication system and the correlated apparatuses. The invention may effectively improve the coding efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular to a codec method, communication system and equipment. Background technique [0002] With the development of wireless communication services and the extensive development and application of Internet technology and services, the diversification and multimediaization of communication services, especially wireless / mobile communication services, the demand for transmission bandwidth of wireless / mobile communication systems is increasing. The transmission capacity of various standards and technologies is far from the demand of wireless high-speed mobile multimedia services. The improvement of transmission bandwidth by many modulation techniques and coding techniques has approached the Shannon limit. Therefore, a multiple-input multiple-output (MIMO, Multiple In and Multiple Out) technology has emerged. [0003] In the prior art, a wireless encoding and decoding scheme based on MIMO is...
