WEIGHT VARIATION AMOUNT ESTIMATING METHOD, WEIGHT UPDATING METHOD, AND COMMUNICATIONS DEVICE

摘要

PPROBLEM TO BE SOLVED: To estimate weight variation amounts among pilot subcarriers. PSOLUTION: A method is for estimating the amount of variations in weight, updated on the basis of a pilot subcarrier included in a reception signal and includes a step of generating a modulated signal, by modulating a received second pilot subcarrier using first weight updated using a received first pilot subcarrier, and a step of calculating the error of the modulated signal for a reference signal, corresponding to the second pilot subcarrier as a weight variation amount between the first pilot subcarrier and the second pilot subcarrier.
