A Discrete Particle Swarm Algorithm for Multipath Selection Scheme in UWB MMSE Receivers

摘要

In a MMSE Ultra-WideBand(UWB) selective rake receiver, the selection of optimal subset of multipath is important for the performance of system. As the optimal solution is NP hard, the Discrete Particle Swarm Optimization Multipath Selection algorithm (DPSO-MSa) was proposed. The DPSO-MSa can get near optimal performance after certain iterations. Simulation results are presents to compare with the conventional algorithm, Genetic Algorithms (GA). The results show that DPSO-MSa has better performance than other algorithms.
