RADIO RECEIVER, RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a radio receiver, a radio communication system, a radio communication method and a program for achieving synchronization in high speed radio communication.

SOLUTION: The radio receiver 200 includes: a sampling part 210 which samples a baseband signal to be transmitted from a radio transmitter by fractional multiples of symbol rate to generate fractional multiple sample data; a providing part 220 in which the radio transmitter provides reference data in which a known symbol system to be arranged in a frame is interpolated by rate of fractional multiples, while reflecting an overall filter response of the radio transmitter and the radio receiver; a calculation part 230 which calculates evaluation data for evaluating a degree of matching of waveform between the fractional multiple sample data and the reference data; an estimation part 240 which estimates reference timing from a shift amount in which the degree of matching of the waveform of the evaluation data shows maximum; and a conversion part 250 which converts the fractional multiple sample data on the basis of the reference timing to restore data of the symbol rate.
