Abstract (en)
[origin: EP1635525A1] A single transmitter transmits K communication bursts in a shared spectrum in a time slot of a time division duplex communication system. Each burst has an associated midamble sequence. A receiver receives a vector corresponding to the transmitted midamble sequences of the K communication bursts. A matrix having K identical right circulant matrix blocks is constructed based in part on the known N midamble sequences. The wireless channel between the transmitter and receiver is estimated based on in part the constructed matrix and the received vector.
