چکیده
This chapter reviews space-time processing methods for CDMA mobile radio applications with emphasis on blind signal detection. We begin with a motivation for the use of blind space-time processing in CDMA. Next, we develop channel and signal models useful for blind processing. We follow this by considering rst space-time single user receivers (ST-RAKE) and then review some basic theory of blind ST-RAKE algorithms. The important problem of multi-user detection (MUD) is considered next which leads to a novel technique allowing the estimation of the minimum-mean-square error linear MUD.

Nonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...

Multiuser detection and space-time processing are two advanced signal-processing techniques for the mitigation of multiple-access interference and intersymbol interference in wireless CDMA communications. The purpose of this work is to investigate techniques for efficient space-time multiuser detection (ST MUD). A companion paper considered batch iterative methods, which assume knowledge of all...
متن کاملArrayed MC-CDMA reception in space-time diffused multipath vector channels
Multi-Carrier Code Division Multiple Access (MC-CDMA) is a modulation scheme that combines the advantages of OFDM and CDMA to provide robustness against frequency selectivity in wireless channels. Arrayed MC-CDMA systems combine MC-CDMA and antenna array technology to harness the spatial and temporal ’signatures’ of received signals, thus making it possible to realize high transmission rates en...
متن کاملBlind Adaptive Decorrelating RAKE (DRAKE) Downlink Receiver for Space-Time Block Coded Multipath CDMA
A downlink receiver is proposed for space-time block coded CDMA systems operating in multipath channels. By combining the powerful RAKE receiver concept for a frequency selective channel with space-time decoding, it is shown that the performance of mobile receivers operating in the presence of channel fading can be improved significantly. The proposed receiver consists of a bank of decorrelatin...
متن کاملDiffused Channel Framework for Blind Space-time Ds-cdma Receiver
In this paper, a blind space-time receiver is proposed to handle point and diffused sources for asynchronous multipath DS-CDMA systems. The receiver is based on a computationally efficient subspace-type algorithm for its joint space-time channel estimation which is insusceptible to near-far problems. The coherency between the sources is removed by a novel temporal smoothing technique operating ...
