Communication channel quality estimation apparatus and communication channel quality estimation method

摘要

A communication channel quality estimation apparatus (3) receives a signal generated using an orthogonal sequence selected from a second number of orthogonal sequences smaller than the first number of orthogonal sequences of the first number The second number orthogonal sequences among the correlation values that are the correlation processing result of the correlation processing unit (302) that performs correlation processing corresponding to the first number of orthogonal sequences, and the correlation processing result of the correlation processing unit (302) And a first power calculator (306) for calculating a first power value using the correlation value synthesized by the synthesizer (310). The first power value is taken as the communication channel quality estimation result.
