Embodiment Construction

[0009] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0010] Currently there is a multi-protocol LDPC encoder that can achieve a smaller area by sharing LDPC encoding units. However, this multi-protocol LDPC encoder cannot adapt to changes in the environment if it does not consider the application scenario. For example: for different business types, there are different delay requirements for the encoder; for different channel environments, different performance requirements for the encoder; for different frame formats, it will also affect the performance of the encoder . Specifically, if the channel environment is good, the performance of the encoder is poor eno...

Abstract

The invention discloses an encoding device and an encoding method. The device comprises a decision device, a parameter register, a check matrix register bank and an encoder, wherein the decision device is used for obtaining parameter information required by the encoding of data according to the service state information and channel state information of the received data; the parameter register is used for storing the parameter information required by the encoding of a service; the check matrix register bank is used for obtaining a check matrix required by the encoding of the service according to the parameter information; and the encoder is used for encoding the received data according to the parameter information and the check matrix, and outputting the encoded data.

Description

technical field [0001] The present invention relates to the communication field, in particular to an encoding device and a corresponding method. Background technique [0002] Frequency band is a precious resource in wireless communication, how to improve spectrum efficiency has always been a research hotspot in wireless communication. LDPC (Low-density parity-check, low-density parity-check code) coding technology has been valued because of its performance close to Shannon's limit. Generally speaking, the performance of LDPC codes with low bit rates and small and medium code lengths is not ideal, but the encoding delay is small; the performance of LDPC codes with high bit rates and long code lengths is excellent, but the encoding delay is long, which is not suitable for high real-time performance. data, such as the transmission of voice services. The purpose of adaptive LDPC coding technology is to combine the characteristics of different code lengths to achieve optimal co...
