WIRELESS COMMUNICATION APPARATUS

摘要

The invention provides precise estimation of a channel response and correct demodulation of an information signal even in the circumstance of being likely suffering interference. The invention includes an error correcting code unit 1, an S/P converting unit 2, a mapping unit 3, an IDFT (Inverse Discrete Fourier Transform) unit (IFFT: Inverse Fast Fourier Transform can be used) 4, a P/S converting unit 5, a GI (Guard Interval) inserting unit 6, preamble (A, B0, B1) storage selecting units 11-a and 11-b, switch units 12-a and 12-b, D/A converting units 13-a and 13-b, radio units 14-a and 14-b and antenna units 15-a and 15-b.
