الملخص

IEEE 802.16d-2004 has been recommended for Worldwide Interoperability for Microwave Access (WiMAX) wireless communication based on Orthogonal Frequency-Division Multiplexing (OFDM) technology and Orthogonal Space-Time Block Code (OSTBC) has been moving toward 4G in wireless communication system. In this paper, optimal pre-coding with only covariance feedback is derived using the minimum pair-wise error probability (PEP) criterion and linear and non-linear pre-coders are designed. The proposed pre-coding only requires statistical knowledge of the channel at the transmitter, which significantly reduces feedback requirements. Both linear and non-linear pre-coders achieved much lower bit error rates (BER) and increased Signal-to-Noise Power Ratio (SNR) for WiMAX OSTBC-OFDM in transmit-antenna and path-correlated channels. The proposed non-linear pre-coder better than the linear pre-coder.
