A channel response estimate is generated from a received signal that comprises two or more different pilot carriers in an Orthogonal Frequency Division Multiplexing (OFDM) communications system. This involves, for each of the carriers, determining a rotation amount that is at least in part a function...http://www.google.fr/patents/US7474611?utm_source=gb-gplus-shareBrevet US7474611 - Reduced complexity channel estimation in OFDM systems
