摘要:
The genetic algorithm is used to synthesize the radiation pattern of the directional circular arc array to minimize the bit error rate (BER) performance in an indoor wireless communication system. By using the impulse response of the multipath channel, the performance of the synthesized antenna pattern on a BPSK (binary phase shift keying) system with phase and timing recovery circuits can be calculated. Based on the topography of the antenna and the BER formula, the synthesis problem can be reformulated into an optimization problem and solved by the genetic algorithm. Numerical results show that the synthesized antenna pattern is effective to combat the multipath fading and can increase the transmission rate of the indoor millimeter wave system
