【摘要】 为了解决在自适应波束形成系统中需要大量的矩阵运算而导致系统实时性能欠佳的问题,提出了一种并行性能较好的混合QR分解SMI算法(MQRD-SMI),给出算法易于DSP实现的一种高速Systolic阵结构,研制岀一种采用多片TS201S并行实现接收ADBF的实验系统.实验结果验证了算法和系统的有效性和实时性.
【Abstract】 In order to solving the problem which ADBF system needs a great deal of matrix computing,by using the mixed QR decomposition approach,a mixed QR decomposition SMI algorithm and systolic array structure which is suitable to be implemented for instantaneous optimal weight extraction are presented.An experimental multiprocessor system with TS201S for parallel receiving ADBF is given.The experimental results show that the algorithm and system are effective and real-time.
