摘　　要：针对自适应波束形成算法实现时硬件资源消耗过多的问题,对传统结构中各子模块的调用方式进行修整,设计出一种资源消耗较小的改良结构.实验结果表明,改良结构在保留原结构良好计算性能的同时,有效地降低了硬件资源消耗.当系统接收端天线数增加到9时,改良结构的DSP Slices的消耗只占到传统实现方法的25%.In order to reduce the cost of hardware resource,the triangular systolic array（TSA）architecture could be modified into a multiplexing architecture called ITSA which could call the same module at the different time.Theoretical analysis and simulation results show that ITSA can reduce hardware cost efficiently.When the number of the arrays is 9,the cost of DSP Slices is the 25% of conventional architecture.
