Abstract The quality of reception of radio signals at the destination is greatly influenced by the type of signaling schemes used and the use of multiple antennas at the output of transmitter and the input of receiver. However, this configuration usually causes InterCarrier Interference (ICI), which leads to distortions. In this paper, the performance of 6×6 multiple antenna beamforming in offset 16, 32 and 64-Phase Shift Keying (PSK) schemes is evaluated using the system model for the received signal developed to reduce distortions. The beamforming is performed on the offset signaling schemes by weighing the transmitted streams with the eigenvalues of the 6×6 antenna channel before the transmission through the 6 multiple antennas over the Rayleigh channel. The distorted signals received are demodulated and filtered by using the square root raised cosine receive filter. These signals are detected and compared with the transmitted bits to evaluate the performance using Bit Error Rate (BER). The results obtained show that as the constellation size of offset PSK schemes increases, the BER values increase and provide better performance than the corresponding conventional schemes.

多天线波束成形在更高星座 PSK 信令方案中的性能

摘要 目的地无线电信号的接收质量受所使用的信令方案类型以及在发射机输出端和接收机输入端使用多根天线的影响很大。但是，这种配置通常会导致载波间干扰 (ICI)，从而导致失真。在本文中，使用为减少失真而开发的接收信号的系统模型来评估偏移 16、32 和 64 相移键控 (PSK) 方案中 6×6 多天线波束成形的性能。在通过瑞利信道上的 6 个多天线传输之前，通过用 6×6 天线信道的特征值对传输的流进行加权，对偏移信令方案执行波束成形。接收到的失真信号通过平方根升余弦接收滤波器进行解调和滤波。检测这些信号并与传输的比特进行比较，以使用误码率 (BER) 评估性能。获得的结果表明，随着偏移 PSK 方案的星座大小增加，BER 值增加并提供比相应的传统方案更好的性能。
