Hybrid antenna selection at transmitter (HAST) scheme for future broadband wireless system

Abstract

In this paper, a new adaptive HAST scheme is proposed for Space Frequency Block Coded (SFBC)-Orthogonal Frequency Division Multiplexing (OFDM) system. This HAST scheme uses subcarrier by subcarrier antenna selection. The performance of the proposed scheme is analyzed for different antenna configurations with average Signal to Noise Ratio (SNR) gain and Bit Error Rate (BER) parameters. The simulation results prove that the performance of conventional SFBC-OFDM system is greatly improved with the proposed scheme.
