分布式发射天线下BPSK Alamouti方案性能分析
Performance Analysis for BPSK Alamouti's Scheme with Distributed Transmit Antennas
摘要
Abstract
An approximate expression of bit error rate (BER) is derived for a circular cell distributed antenna system with space-time block coding based on Alamouti's scheme and utilizing binary phase shift keying (BPSK) modulation.The analysis is carried out on considering the effects of path loss,log-normal shadowing,multipath fading and background noise.A simulation is carried out under the condition of two transmit and one received antennas,single-path Rayleigh fading channels,antenna spacing of 200 m,and standard deviation of shadowing of 8 dB.The simulation results show that,the numerical results match the simulation results well,and at the BER of 3× 10-1,the proposed method is superior by about 1.4 dB to the traditional methods in bit signal-to-noise ratio.关键词
