PROBLEM TO BE SOLVED: To improve transmission efficiency by shortening delay caused by various kinds of initial setting of an equalizer and performing equalizing with a shortest preamble. SOLUTION: This receiver is provided with RF parts 2a and 2b converting the frequency of received data from antennas 1a and 1b, comparing part 3 selecting the larger output of the RF parts 2a and 2b, carrier detecting parts 4a and 4b detecting the starting point of received data on the basis of the output signal of the comparing part 3 and ending demodulation of an equalizer part by receiving a demodulated data end signal, OR circuit 5a outputting the OR of outputs of the carrier detecting parts 4a and 4b, AND circuit 6a outputting the output signal of the RF part 2a while the output signal of the carrier detecting part 4a is active, AND circuit 6b for outputting the output signal of the RF part 2b while the output signal of the carrier detecting part 4b is active, OR circuit 5b outputting the ORed result of the AND circuits 6a and 6b, and equalizer part 7 inputting the output from the OR circuit 5a and performing equalizing processing of the inputted received data. |
