Interference noise estimation method, reception processing method, interference noise estimation apparatus, and receiver, in multicarrier communications system

摘要

To make it possible to estimate interference noise power with high accuracy even when channel variations are present in a frequency domain and a time domain, in a multicarrier communications system in which pilot signals allocated at different subcarrier frequencies in a predetermined transmission frequency band are transmitted, average values between pilot signals received at different symbol timing periods and at different subcarrier frequencies are obtained, and interference noise is estimated based on a difference between the average values.
