Abstract:
A method for assessing transmission channels of a wireless telecommunications system comprising:transmitting messages between one or more transmitters and at least one first receiver of the telecommunications system via at least one of the transmission channels of the wireless telecommunications system; receiving a first message transmitted by a first transmitter of the one or more transmitters at the first receiver; receiving at least one further message transmitted by at least one of the first transmitter, and a further one of the one or more transmitters to at least one further receiver, the at least one further message being transmitted in a same transmission direction as the first message; estimating channel impulse responses using specified information configured as a training information sequence contained within any one or more of the transmitted messages; and assessing the at least one or more transmission channels based on a correlation of the channel impulse responses.
