Multiuser Detection for MIMO CDMA Systems
MIMO is a technique to increase data rate significantly with multiple antennas at both the transmitter and receiver. MIMO takes the advantage of random fading and multipath delay spread. MIMO systems will need to function reliably in interference limited environment in order to be effective. CDMA systems are designed to operate in an interference free environment and for this reason it is used ...

متن کاملNonlinear 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...
متن کاملMultiuser detection for CDMA systems
Present day direct sequence code division multiple access (DS/CDMA) systems treat each user separately as a signal, with all ofthe other users representing interference or noise. Potentially significant capacity improvements can be achieved if the negative effect that each user has on the others is cancelled. In other words, joint detection (multiuser detection), rather than separate detection,...
