摘要

在本文中，我们扩展了时间反转(TR)预编码技术和乒乓优化脉冲整形(POPS)波形优化算法的联合使用，以设计多输入单输出正交频分复用(MISO-OFDM)系统的最佳发射和接收波形。设计过程以TR-MISO通道散射函数的完整表征为基础，然后实施持久性有机污染物方法。数值分析表明，与TR-SISO-OFDM系统中的优化波形和TR-MISO-OFDM系统中的PHYDYAS波形相比，TR-MISO-OFDM系统中的优化波形在信噪比(SINR)方面带来了显著的增益。

Efficiency of the TR Technique and the POPS Algorithm for Waveform Optimization in MISO-OFDM Systems

In this paper, we extend the joint use of the Time Reversal (TR) precoding technique and the Ping-Pong Optimized Pulse Shaping (POPS) waveform optimization algorithm to design optimal transmit and receive waveforms for Multiple Input Single Output-Orthogonal Frequency Division Multiplexing (MISO-OFDM) systems. The design process banks on a full characterization of the scattering function of the TR-MISO channel, followed by the implementation of the POPS approach. Numerical analysis reveal a significant gain, brought by the optimized waveforms in TR-MISO-OFDM systems, in terms of Signal to Interference plus Noise Ratio (SINR), compared to the optimized waveforms in TR-SISO-OFDM systems and the PHYDYAS waveform in TR-MISO-OFDM systems.
