WIRELESS RECEIVER AND WIRELESS TRANSMITTER

摘要

PROBLEM TO BE SOLVED: To provide a technique calibrating a broadband transmission/reception signal with high accuracy without deteriorating the communication quality of the transmission/reception signal and causing reduction in the throughput. SOLUTION: Each of signal multiplexing sections 112 multiplexes a reference signal on a received signal to calculate an amplitude error and a phase error given by a wireless reception system 113. The reference signal multiplexed by each of the signal multiplexing sections 112 is one or more subcarrier signals whose frequency is orthogonal to the frequency of a multicarrier signal. The frequency of the reference signals in this case is orthogonal to that of the other subcarriers in the received signals. An inter-wireless-system error calculation section 126 separates the reference signals multiplexed on the received signals, compares the respective received signals and calculates errors of the respective received signals. An error correction section 122 corrects the received signals of respective wireless reception units 110 on the basis of the errors of the received signals calculated by the inter-wireless-system error calculation section 126.
