<p>A received power estimating method in which received power is estimated by using a ranging code. The received power estimating method is characterized by including a modulation step of performing predetermined modulation processing for the ranging code, a phase correction step of generating the amount of delay at predetermined intervals within a predetermined delay range and performing a phase correction to the result of the modulation processing on the basis of the delay amount generated at the predetermined intervals and the frequency of the sub-carrier to which the ranging code is assigned to obtain a phase correction signal, a cross-correlation value calculating step of calculating the cross-correlation value between the received signal and the phase correction signal, and an integration step of integrating the predetermined range's worth of the calculated cross-correlation value, wherein the received power is estimated on the basis of the result of the integration.</p> |
