Low complexity polar product coding for decode-and-forward cooperative relay channel
摘要
Abstract
The study was performed based on the concept of polar coding to solve the problem of high encoding and decoding complexity of decode-and-forward ( DF) cooperative relay channels obeying the time division half-duplex mode. A DF relay channel model for cooperative communications was established, and then the achievable rate of the DF cooperative relay channels was analyzed. Furthermore, according to the analysis, a polar product coding scheme with equal time slots was designed based on the polar coding concept. Under the scheme, the received data from the source can be decoded reliably at the relay. With the help of the side information sent from the relay, the destination can estimate the transmitted data from the source correctly. The proposed polar product coding scheme has a low coding/decoding complexity. The simulation results show that, under the low signal to noise ratio (SNR) , the scheme can obtain the better bit error rate (BER) performance compared to direct link.关键词
