QRD-LSL algorithm suitable for implementation on D.S.P. [articol]

Abstract

This paper deals with modifications brought to the QRD-LSL algorithm presented in [5], in order to implement it on Digital Signal Processor (DSP). It is necessary to choose a powerful processor, with a parallel architecture that allows several instructions to be executed simultaneously. This is the main reason for choosing Motorola SC140 processor. In addition, we have structured the algorithm in a way to allow a high complexity algorithm to be run in real-time in a specific application. The paper presents the main features of this DSP and then makes comparisons between the original algorithm, described in [1] and the improved version with low complexity.
