Low-Density Parity Check Codes
Joseph, Jeevitha / Rekh, A. Shobha
Coded modulation is a bandwidth-efficient scheme that integrates channel coding and modulation into one single entity to improve performance with the same spectral efficiency compared to uncoded modulation. Low-density parity-check (LDPC) codes are the most powerful error correction codes (ECCs) and approach the Shannon limit, while having a relatively low decoding complexity. In communication system signal is transmitted and received at the o...
