摘　　要：近年来,随着软件无线电的发展,用于软件无线电平台中的多DSP并行结构受到越来越多的关注,因为这种结构能提高数字信号处理的速度。提出了一种适合在该平台上并行运算的算法,以多阶FIR滤波器为例,验证了算法,并探讨算法的性能,给出了该算法在多处理器条件下,与单处理器处理结果的比较。对选取合适的软件无线电中频处理多处理器平台具有一定的参考价值,并对舰载软件无线电的实现提供了科学参考。Recently, with the development of the software radio, parallel DSP architectures used on the software radio platform have gained much attention, since they offer the potential to speed up the computation of digital signal processing algorithms. Based on an improved network structure for software radio. This paper presents a parallel algorithm for FIR filter and a multiprocessor architecture suitable for the processing applications. It also investigates parallel processing systems in terms of performance and efficiency. The implementation of the parallel algorithm is discussed and results are given to show the performance of the ,paraUel system compared to a single processor system. This idea is suitable for the implement of the functions on the improved software radio platform.
