Is BCH decoder really necessary in DVB-T2 receiver
暂无分享,去创建一个
The digital video broadcasting-second generation terrestrial (DVB-T2) uses both low-density parity check (LDPC) and BCH error-correction codes. Since the LPDC decoder can correct more errors with more iterations, it is important to know the advantage of using the BCH decoder in a DVB-T2 receiver. This paper addresses this issue and gives some simulation results. The results show that at higher SNR environment, the BCH decoder may not be necessary.
