摘要: The present invention provides a method of characterizing frequency response transmission channel between transceiver and subscriber unit. includes once per predetermined interval time, the transmitting signal including multiple carriers, plurality carriers training symbols, information symbols. unit generates estimates at frequencies each time. are converted into time domain generating an impulse responses filtered over intervals A profile is determined from responses. to interpolator. characterized generated interpolator estimates. filtering can include averaging accumulating or weighted be dependent upon phase error responses, and/or amplitude
