Patent Searching and Data


Title:
WIRELESS COMMUNICATION DEVICE AND ITS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2007/119487
Kind Code:
A1
Abstract:
A wireless communication device is provided to obtain a frequency diversity gain, so that transmission characteristics can be improved. In this wireless communication device, a modulator (201) modulates transmitting data by a prescribed modulation system, an inserting unit (202) inserts “0” into the data so as to generate desirably modulated data, an S/P convertor (203) converts the desirably modulated data to parallel ones, a DFT unit (204) converts time domain data to frequency domain data by N-point DFT processing, a data mapping unit (205) carries out mapping N-point frequency domain data to M-point ones, an IDFT unit (206) converts frequency domain data to time domain data by M-point IDFT processing, a CP adding unit (207) adds a CP to every data block, and a P/S converter (208) converts parallel data to serial ones.
