Estimation of transmission channels in communication systems for wireless telecommunication

Transmitting and receiving appliances (transmitters and receivers) are used in message systems having a message transmission path between a message source and a message sink for message processing and transmission, for those appliances in which The correlations of different channel impulse responses are used to improve, simplify and optimize the assessment of wire-free transmission channels in telecommunications systems. In particular, the different channel and pulse responses are correlated by identifying a similarity between the different responses and driving a mean channel impulse response from the different channel impulse responses when they are identified as similar.
