Design of Quasi-cyclic RA-like Codes Based on Expansions through Two Steps
一种基于二次扩展的准循环类RA码编码器的设计

A new design of encoder was proposed for RA-like codes which take the advantage of the linear encoding complexity characteristic of RA codes.The method is based on special expansions through two steps.The code is quasi-cyclic to save required memory,and has high flexibility with respect to the design of code length and rate.The encoding algorithm is based on recursions,so the encoding complexity is linear equation of code length.Simulation results demonstrate that over an additive white gauss noise channel,...
