PROBLEM TO BE SOLVED: To provide a communication apparatus capable of further improving channel estimation accuracy by suitably separating multiplexed reference signals.SOLUTION: A base station device 1 includes a channel estimation part 10 for estimating respective channel characteristics of a plurality of reception signals. The channel estimation part 10 subjects the transmission path frequency response of a reception multiple signal obtained by multiplexing a plurality of reference signals by cyclic shift to discrete cosine transform, and estimates the channel characteristics based on a transmission path time response obtained thereby. |
