Delay-limited Protograph Low Density Parity Codes for Space-Time Block Codes
Thuy Vu Minh Nguyen, Cuong Pham, Hieu Trung Nguyen · 2018
This paper presents a framework to design protograph low density parity check (LDPC) codes for wireless communications where Alamouti space time block code (STBC) scheme is exploited to combat with the fading effect and the number of decoding iterations is limited. The decoding threshold of the resulting protograph code is about 0.7 dB better than that of the state-of-the-art code in the literature. The simulation of the proposed code is reported, and simulation results confirm the analytical advantages of the design. No error floor is found down to frame error rate (FER) of 10-6.
