Performance analysis of W-CDMA algorithms on a vector DSP

Abstract

The software defined radio principle is a key technology for mobile devices as well as base stations. Especially femto cells for small-distance indoor environments are of major interest. This paper presents an evaluation of the embedded vector processor (EVP) as one possible principal component of an SDR femto-sized base station. We present results of our performance analysis of selected W-CDMA baseband algorithms. We give a detailed description of the mapping of a SIMO chip- equalizer and an HSDPA downlink spreader on the EVP. The achieved performance demonstrates that the EVP may satisfy real-time requirements of current mobile communication standards.
