ABSTRACT:
An RF receiver includes a plurality of OFDM modules. The OFDM modules include receiver antennas for substantially simultaneously receiving a plurality of transmission signals transmitted via a single frequency band having a plurality of sub-channels. Further included is a channel estimation module connected to the plurality of OFDM modules, and a channel compensation module connected to the channel estimation module and the plurality of OFDM modules. For each sub-channel, the channel estimation module is capable of estimating channel frequency responses affecting the transmission signals, and the channel compensation module is capable of compensating the transmission signals according to the estimated channel frequency responses. The receiver allows an improved transfer rate per frequency band.
