Abstract

A single transmitter transmits K communication bursts in a shared spectrum in a time slot of a time division duplex communication system. The system associated with N
midamble sequences. 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 N 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 one of the N
blocks and the received vector.
