RECEPTION DEVICE AND RECEPTION METHOD

摘要

A receiver includes a propagation path estimation unit which produces a channel impulse response estimation value from a received signal, a replica signal creation unit which creates a replica signal as a replica of a transmitted signal based on the received signal, a time period setting unit which sets time periods into which the channel impulse response estimation value is divided, a received signal extraction unit which extracts received signals of the time periods set by the time period setting unit using the replica signal created by the replica signal creation unit, a combining unit which iterates a process for combining the signals of the time periods extracted by the received signal extraction unit, and a demodulation processing unit which performs a demodulation process for the signals combined by the combining unit. The number of time periods set in at least one iterative process is different.
