The method samples and stores the course of the training signal at the receiving end, at specific times. An estimated impulse response or transfer function of the channel is then deduced. The discrepancy between measured and calculated values is worked out and the estimate is varied in steps until the discrepancy is minimised. A functional unit (50) which produces a correlative estimate (h') of the coefficients of the channel impulse response, feeds another unit (52). This unit performs an iteration to obtain an improved estimate (h") and optionally a channel state information signal (CSI). |
