| Abstract: | The computer simulation modeling is considered as an independent knowledge system. By use of communication system modeling methodology, a precise simulation model of OFDM system working under time dispersive channel was established. An improved Jakes simulator was adopted to realize l-path Rayleigh fading and the tapped-delay-line representation of a frequency-selective and time- variant channel in the equivalent complex baseband was applied to design time varying dispersive channel model. System parameters were set according to 802.1 la standard and BER performance of system working under AWGN channel, 1-path Rayleigh channel and multipath Rayleigh channel was proposed respectively. |
