联合空时信号处理已被认为是降低甚高比特率移动的无线电通信系统中出现的码间干扰和同信道干扰的关键。开发能够在时域和空域模拟移动的无线电传播场景的硬件模拟器对于评估时空信号处理方案的实时性能是必不可少的。本文概述了一个复杂的基带平台开发的时空移动的无线电信道仿真。该平台包括一个复杂的基带衰落/阵列响应模拟器，数字信号处理器（DSP）板，和一个通用的参数估计器，使用脉动阵列实现的递归最小二乘（RLS）算法。使用开发的平台进行的实验结果，以确认系统的正常运行。
Joint spatial-temporal signal processing has been recognized as the key to reducing the effects of the intersymbol and cochannel interference seen in very high bit-rate mobile radio communications systems. Developing hardware simulators that can simulate mobile radio propagation scenarios in time and space domains is essential for evaluating the real-time performance of spatial-temporal signal processing schemes. This paper outlines a complex baseband platform developed for spatial-temporal mobile radio channel simulations. The platform consists of a complex baseband fading/array response simulator, a digital signal processor (DSP) board, and a general-purpose parameter estimator that uses systolic array implementation of the recursive least square (RLS) algorithm. Results of experiments conducted using the developed platform are presented to confirm the proper operation of the system.
