Described is a transmission system for transmitting a multicarrier signal from a transmitter (10) to a receiver (20). The multicarrier signal comprises a plurality of subcarriers. The receiver (20) comprises a channel estimator (28) for estimating amplitudes of the subcarriers and for estimating time...http://www.google.com.hk/patents/US7054354?utm_source=gb-gplus-share專利 US7054354 - Multicarrier transmission system with reduced complexity leakage matrix multiplication
