摘要

本文分析了采用M-QAM星座的N×1多输入单输出MISO系统的最佳双发射天线选择方案的性能。利用瑞利衰落信道上的阶统计量，导出了系统中断概率和符号错误率的精确和渐近封闭表达式。这种选择技术在实现全分集顺序的同时，降低了与多个发射天线相关的系统的复杂性和成本。此外，数值结果表明，与Alamouti空时分组编码相比，BTTAS波束形成方案实现了完全的分集，并提供了显著的编码增益。

Order Statistics Based Best Two Transmit Antenna Selection for N × 1 MISO System

In this paper, we analyze the performance of the best two transmit antenna selection (BTTAS) scheme for N×1 multiple-input-single-output (MISO) system employing M-QAM constellation. The exact and asymptotic closed-form expressions of outage probability and symbol error rate (SER) are derived using order statistics over the Rayleigh fading channel for the considered system. This selection technique reduces the complexity and costs of the system associated with multiple transmit antennas while achieving the full diversity order. Further, numerical results show that the proposed BTTAS beamforming scheme achieves full diversity and provides a significant coding gain in comparison to the Alamouti space-time block code.
