Particle Swarm Optimisation Aided MIMO Multiuser Transmission Designs
Bio-inspired computational methods have found wide-ranging applications in signal processing and other walks of engineering. The main attraction of adopting bio-inspired computational intelligence algorithms is that they may facilitate global or near global optimal designs with affordable computational costs. In this contribution, particle swarm optimisation (PSO) is invoked for designing optim...
متن کاملApproximate Minimum Bit - Error Rate Multiuser Detection
— The minimum mean-squared-error (MMSE) linear multiuser detector [1–2] is popular because of its good performance and amenability to adaptive implementation. However , there are circumstances in which the linear detector that minimizes bit-error rate (BER) can significantly outperform the MMSE detector. We propose a low-complexity adaptive algorithm for approximating the minimum-BER linear mul...
متن کاملParticle Swarm Optimisation Aided Multiuser Transmission Schemes for MIMO Communication
Bio-inspired computational methods have found wide-ranging applications in signal processing and other walks of engineering. In this contribution, particle swarm optimisation (PSO) is invoked for designing optimal multiuser transmission (MUT) schemes for multiple-input multiple-output communication. Specifically, we consider the minimum bit-error-rate (MBER) linear MUT using PSO and we design a...
متن کاملParticle Swarm Optimisation Aided MIMO Transceiver Designs
Multiple-input multiple-output (MIMO) technologies are capable of substantially improving the achievable system’s capacity, coverage and/or quality of service. The system’s ability to approach the MIMO capacity depends heavily on the designs of MIMO receiver and/or transmitter, which are generally expensive optimisation tasks. Hence, researchers and engineers have endeavoured to develop efficie...
متن کاملCriteria for Minimum Bit Error Rate
The stability behaviour of the iterative decoding (ID) of Turbo-Codes and its innuence on the overall performance are discussed. Several criteria to characterize the ID are proposed and the most reliable ones are determined. These criteria are used to partition the transnitted blocks into stable and unstable ones. For unstable blocks the decoding step is determined which most likely produces a ...
