| Abstract: | An improved Jakes simulator is adopted to realize 1 - path Rayleigh fading and the tapped -delay - line representation of a frequency - selective and time - variant channel in the equivalent complex base-band is applied to design time varying dispersive channel model. System parameters are set according to 802. 11a standard and BER performance of the system working in AWGN channel, 1 - path Rayleigh channel and multipath Rayleigh channel is analyzed respectively. |

| Keywords: | Jakes simulator time varying dispersive channel simulation modeling design. |
