二维到达角和极化参数的并行化设计

针对无线电波的信号频率、二维到达角和极化参数联合估计算法的运算量大、计算时间长，且不能满足实时性要求的问题，提出了对该算法进行并行化设计的解决方法。通过对联合估计算法的数学模型和串行算法的分析，设计并实现了通用并行算法。经在4台同构处理器上进行测试，表明该并行算法能有效减少计算时间，使加速比达到2倍以上。
关 键 词 二维到达角; 极化参数; 并行算法; 复数矩阵; 加速比; 效率

Abstract Two dimension arrived angle and polarization parameter's estimate arithmetic in radio wave have very important station in some applied domain. But it's needed large numbers of operations and a very long times, which can't suit for real-time need. Because of the real time needs of arithmetic, we analyzed, designed and implemented its parallel arithmetic. Then we tested the serial arithmetic, and tested the parallel arithmetic in four isomorphic computers, got higher acceleration ratio and efficiency. So it expresses the parallel arithmetic is effective.
Key words two dimension arrived angle; polarize parameter; parallel algorithm; plural matrix; acceleration ratio; efficiency
