PSO and APSO for optimal antenna locations in indoor environment
Intelligent Green Building and Smart Grid（2014）
摘要
A novel optimization procedure to allocate the location of receiver antenna in ultra wideband (UWB) wireless communication systems in indoor environment is presented. The impulse responses of different antenna locations are computed by ray-tracing techniques. By using the impulse responses of these multi-path channels, the bit error rate (BER) performance for binary pulse amplitude modulation (BPAM) impulse radio UWB communication system is calculated. Based on the BER performance, the outage probability of arbitrary region of transmitters for any given location of the receiver antenna can be computed. Particle swarm optimizer (PSO) and asynchronous particle swarm optimization (APSO), which can minimize the outage probability, are used to find the optimal location for the receiver antenna in the indoor environment. Numerical results show that the performance for reducing BER and outage probability by APSO and PSO is similar. The numerical results also show that the APSO outperforms the PSO in convergence speed.
