碩士 === 國立高雄應用科技大學 === 電子工程系 === 99 === In the communication systems, due to noise interference of signal transmission through channel, so the signal will need to be handled at the receiver, applying an equalizer recovering the received signal should be considered. Inter-symbol interference (ISI) is an important factor which affects the performance of communication systems, so that the originally transmitted symbols can be recovered correctly at the receiver, an equalizer can effectively eliminate ISI caused by band-limited channel or multipath. In this thesis, we propose a self adaptive bacterial foraging oriented by particle swarm optimization (SABF-PSO) approach, to update the adaptive channel equalizer weights which are optimized. Finally, from the simulation results are given to verify the effectiveness of the proposed method.
