Abstract
A cellular communication system comprises a Multiple-In Multiple-Out (MIMO) transmitter and receiver. The MIMO transmitter comprises a message generator for generating MIMO messages comprising selected training sequences and transceivers transmitting the messages on a plurality of antennas. The training sequences are selected by a midamble selector from a set of training sequences in response to an associated antenna on which the message is to be transmitted. The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver comprises a transmit antenna detector which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.
