Abstract  Abstract

A receiver situated in a communication network comprising a plurality of MIMO-OFDM transmitters, the MIMO-OFDM receiver comprising: at least one receive antenna (734, 735) and processing means configured to: at each of at least one receive antenna (734,735), sample a received signal to produce a respective set of time domain samples, determine at least one coarse synchronization position; and at each of the at least one receive antenna (734,735): perform a frequency domain correlation between at least one received common synchronization sequence extracted from synchronization sub-carriers (9,27) in the received signal and a corresponding common synchronization sequence of a respective one of a plurality of transmit antennas (21,23) to identify a plurality of candidate correlation peaks; select the M strongest correlation peaks for further processing; at each of the M strongest correlation peaks, reconvert time domain samples into frequency domain components and processing dedicated pilot sub-carriers (12,25), these containing transmitter specific information, to identify a transmitter (21,23) associated with each correlation peak; determine a C/I (carrier-to-interference) value for each transmitter (21,23) thus identified; and select the transmitter (10) having the largest C/I determined for any of the at least one receive antenna (734,735).
