ABSTRACT This paper focuses on the design of a multi-user receiver structure for the reverse link of a Wideband Code-Division Multiple-Access (WCDMA) communication system. The detection is based on a ML-based channel estimation algorithm. Once a composite Channel Impulse Response (CIR) of each user is estimated, it is directly used in the detection process instead of first extracting the individual channel parameters, such as path delays and attenuation factors. The paper presents a framework that facilitates a computationally efficient solution to the combined problem of channel estimation and detection in a multiuser multi-path environment. The performance of the different detectors is evaluated in terms of bit error probability using the estimated composite CIR. | ||||
