Information transmission method and communication equipment

Abstract

The invention provides an information transmission method and communication equipment. The information transmission method comprises the following steps: determining the quantity N of filling bits according to effective information bit quantity M of coded blocks and effective input port quantity L of polarization code encoders, wherein M and L are positive integers, and N is the difference betweenL and M; determining the input bits inputted in the polarization code encoders, wherein the input bits comprise M effective information bits and N filling bits; inputting the input bits in the polarization code encoders for encoding through the L effective input ports to obtain encoded bits according to mapping relation of the L effective input ports and the input bits ; and transmitting the encoded bits. Therefore, when the effective information bit quantity of the coded blocks is smaller than the effective input port quantity of the polarization code encoders, polarization codes are successfully adopted for encoding by using a bit filling method, so that the successful information transmission is ensured.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly, to a method and a communication device for transmitting information. Background technique [0002] Polar Code (Polar Code) is a coding technology that has been paid more and more attention in recent years. It changes the characteristics of the original channel by constructing a composite channel, so that the capacity of the composite channel is more close to the high and low poles, so it is called "polar code". Due to this characteristic, polar codes can be adapted to randomly distributed original channels through appropriate coding design, and achieve good performance under many different channel implementations, and approach the channel capacity. Moreover, it can greatly reduce the complexity of the receiver through interference elimination decoding, which is very beneficial for realization. [0003] Existing polar code encoders generally adopt a fixed encoding stru...

Problems solved by technology

However, when the number of effective information bits of the coded block is less than the number of effective input ports of the polar code encoder, the polar code cannot be used for encoding, resulting in the inability to transmit the coded block using the polar code
