針對無線電波的信號頻率、二維到達角和極化參數(shù)聯(lián)合估計算法的運算量大、計算時間長，且不能滿足實時性要求的問題，提出了對該算法進行并行化設(shè)計的解決方法。通過對聯(lián)合估計算法的數(shù)學模型和串行算法的分析，設(shè)計并實現(xiàn)了通用并行算法。經(jīng)在4臺同構(gòu)處理器上進行測試，表明該并行算法能有效減少計算時間，使加速比達到2倍以上。

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
