Patent ID: 8463213

Claim:
A reception method comprising: receiving a plurality of modulated signals using a plurality of antennas, wherein: at least one modulated signal among the received plurality of modulated signals includes a frequency offset estimation signal, a channel fluctuation estimation signal, a first gain control signal, and a second gain control signal, the first gain control signal is arranged ahead of the frequency offset estimation signal, and the second gain control signal is arranged subsequent to the frequency offset estimation signal and ahead of the channel fluctuation estimation signal; controlling a gain of the at least one modulated signal using the first gain control signal and the second gain control signal; correcting a frequency offset of the at least one modulated signal using the frequency offset estimation signal; estimating a channel fluctuation of the at least one modulated signal where the frequency offset is corrected, using the channel fluctuation estimation signal; separating the at least one modulated signal where the frequency offset is corrected, from the received plurality of modulated signals, using the estimated channel fluctuation; and demodulating the separated at least one modulated signal.
