摘要： An OFDM receiver includes a timing error detection unit that determines error information based on a difference between receiving timing of a desired signal from a counterpart transmitter and receiving timing of an undesired signal from a non-counterpart transmitter. The timing error detection unit includes a pilot signal detection unit configured to detect a pilot signal of the desired signal and a pilot signal of the undesired signal from an FFT-processed received signal; a first converting unit configured to convert a frequency-domain channel estimate derived from the pilot signal of the desired signal to a first time-domain channel impulse response; a second converting unit configured to convert a frequency-domain channel estimate derived from the pilot signal of the undesired signal to a second time-domain channel impulse response; and an error information determination unit configured to determine the error information based on the first and second channel impulse responses.
