Abstract:
    The invention relates to a wireless OFDM deficit inquire algorism WORDRRACP, based on channel prediction, used in span group distribution of OFDM system, wherein via analyzing the state of time-variable Rayleigh fading channel, base station can accurately judge the instant state of each terminal at each OFDM sub channel, to distribute the effective sub band resource, to optimize the system resource utilization. And the WODRRACP method can distinguish different levels of QoS demands, to confirm the equitable property of multi-service share wireless bandwidth. And said method can apply the high-speed service of wireless group network based on OFDM technique.
