摘要：A pilot signal is estimated by using the sampling theorem to estimate noisepower in a stable manner without depending on the signal to noise ratio. A pilot signalestimation section obtains an estimated pilot signal by using the sampling theorem
according to a plurality of received pilot signals sampled in the frequency domain by asampling processor. A noise power estimation section estimates noise power by applyingstatistical averaging to the difference between the received pilot signal received from thesampling processor and the estimated pilot signal received from the pilot signalestimation section.
