摘要

针对空间频率块编码(SFBC)-正交频分复用(OFDM)系统,提出了一种新的自适应HAST方案。该方案采用子载波对子载波天线进行选择。采用平均信噪比(SNR)增益和误码率(BER)参数,分析了该方案在不同天线配置下的性能。仿真结果表明,该方案大大提高了传统SFBC-OFDM系统的性能。

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