Title
Pilot-assisted data recovery for OFDM systems with blind selected mapping scheme and space-frequency block coding
Abstract
Pilot-assisted blind selected mapping (PB-SLM) scheme for multiple input single output (MISO) orthogonal frequency division multiplexing (OFDM) systems is proposed. At the receiver, individual values of autocorrelation of two consecutive pilot sub-channel responses are evaluated for all the phase sequences available at the transmitter. The phase sequence index corresponding to the highest value of autocorrelation is considered as the side information (SI) and used for data recovery. Due to the robust phase sequence selection based on pilot symbols, data decoding performance of the PB-SLM scheme is substantially better than that of the recent blind SLM (B-SLM) scheme for MISO OFDM systems with space-frequency block coding, which is based on sub-optimal maximum likelihood of data symbols, and almost identical with that by the simplified SLM scheme with perfect SI. Moreover, computational complexity is significantly lower than that of the B-SLM scheme.
