As compared to uncoded unitary space-time modulation (USTM), channel coded USTM has received increased attention for its large coding gain. However, low-density parity-check (LDPC) coded USTM has only received limited attention. This paper proposes a scheme of combining LDPC code with USTM for noncoherent MIMO communication system over Rayleigh flat fading and additive white Gaussian noise (AWGN)...
Orthogonal frequency division multiplexing (OFDM) has attracted much attention as it is convenient to implement and robust to multiple path fading. However, the system performance of OFDM will be degraded seriously in high-speed wireless communications, since it is much sensitive to severe inter-carrier interference (ICI) caused by high-speed vehicles. Recently, a novel modified OFDM system, called...
