摘要

Rateless code is applied to the wireless communication system, to solve the rate mismatch problem of fixed rate code due to the channel change. There is a good compromise of Accumulate Rateless Code (AR code) in rateless family on the decoding performance and complexity. But Log Likelihood Ratio-Belief Propagation (LLR-BP) decoding algorithm is based on the large consumption of time and resources....
