This paper presents a robust multiuser detection technique for direct sequence-code division multiple access (DS-CDMA) systems over Nakgami-m fading channels in the presence of impulsive noise. Robust M-decorrelating detector to demodulate non-coherent DPSK signals is implemented by using the particle swarm optimization (PSO) algorithm. The PSO algorithm is(More)
Experimental results have confirmed the presence of impulsive (heavy-tailed) noise in different wireless communication channels. In direct sequence-code division multiple accesses (DS-CDMA) systems, the signals are transmitted over multipath channels that introduce fading. Multipath fading along with multiple access interference (MAI) and inter-symbol(More)
Cognitive consistency analysis aims to continuously monitor one's perception equilibrium towards successful accomplishment of cognitive task. Opposite to cognitive flexibility analysis – cognitive consistency analysis identifies monotone of perception towards successful interaction process (e.g., biometric authentication) and useful in generation of(More)
