BLIND CHANNEL IDENTIFICATION FOR MULTIRATE CDMA SYSTEMS

By Hongbo Yan and Sumit Roy

Abstract

In this paper, we propose a unified approach to blindly identify channels for multirate CDMA systems- both multiple code (MC) and variable processing gain (VPG) systems are considered. A time-domain subspace approach to blind channel estimation introduced in [3] is generalized to the multi-rate case. Performance evaluation is conducted based on the normalized root mean square error (NRMSE) with an appropriate single-rate as a baseline for comparison. 1
