Implementation of an RTLS blind equalization algorithm on DSP

Abstract

Blind equalization has been a very active area of research during the last years. Research is mostly focused on performance without too much attention on the complexity of the presented techniques. However, the high complexity of these blind algorithms coupled with the high data rates of mobile telecommunications may hamper a practical implementation. Recently we presented a recursive total least squares (RTLS) algorithm which has a reduced computational complexity (P. Vandaele and M. Moonen, 1997). We integrate this algorithm into a transmitter/receiver structure and present some results on the implementation of the algorithm in DSP.
