【摘要】 自适应阵列处理技术因为能够大大提高电子系统的抗干扰能力、可靠性、分辨能力等重要指标而得到越来越广泛的应用。但其实时处理由于算法的巨大运算量而难以实现。ＣＯＲＤＩＣ算法具有将多种复杂函数的计算转变为统一的简单的移位加法操作，并适于ＶＬＳＩ硬件实现的特点，为人们设计既面向自适应抗干扰算法结构，又面向算法基本运算的ＶＬＳＩ专用阵列处理机来完成实时自适应抗干扰处理任务提供了新的途径。本文介绍ＣＯＲＤＩＣ算法的基本原理，并研究了ＱＲ分解最小二乘算法基于ＣＯＲＤＩＣ算法芯片的实现。更多还原

【Abstract】 Coordinate Rotation Digital Comprter (CORDIC)has drawn more and more attentionnowadays,as it offers a unified iterative formulation to efficietly evaluate many complex fuctions.Thisregular,unified formulation makes the CORDIC technique a good candidate for desiging a specific VLSIarray processor,which matches not only the architecture but also the basic valuation of the adaptive anti-jam algorithm.The CORDIC based VLSI array prccssor can meet the need of real-time adaptive processingapplication for its high efficiency and high throughput ratio.This paper discusses how to implement theQRD-LS algorithm based on the CORDIC chip after a brief survey of this novel algorithm.更多还原
