最小二乘Systolic阵有限字长运算的理论分析

Theoretical analysis of quantization effects in RLS systolic array

本文针对McWhirter提出的最小二乘Systolic结构进行了有限字长误差分析,对引起误差积累的各种因素分别做了理论推导,证明了误差积累是有界的,并且误差积累的上界是不大的。本文还给出了计算机模拟的结果,它与理论结果是一致的。

The quantization effects of RLS Systolic array introduced by McWhirter are separately analysed and calculated for three factors. It is proved that the error accumulations are limited, and the maximum of error is not so large. Finally, an adaptive interference cancelling system is simulated by the RLS Systolic array. The simulant results agree with the theoretical analysis.
