In wireless communications, spatial diversity techniques, such as Space-Time Block Code (STBC) and Single-Input Multiple-Output (SIMO), are employed to strengthen the robustness of the transmitted signal against channel fading. This paper studies the performance of protograph-based Low-Density Parity-Check (LDPC) codes with receive antenna diversity. The authors first propose a modified version of the Protograph EXtrinsic Information Transfer (PEXIT) algorithm and use it for deriving the threshold of the protograph codes in a Single-Input Multiple-Output (SIMO) system.
