| Abstract(in English) | The surface acoustic wave has a definite advantage in the Fourier transform for amount of wave of OFDM that is converted into the OFDM signal and received in power consumption and has a super-high-speed operation processing performance. The operation speed of the SAW Chirp-Z transform processor composed of SAW Down Chirp Filter of bandwidth 100MHz and N=2,048 becomes 5.5GFLOPS. The condition that the temperature coefficient of the delay time of SAW Down Chirp Filter becomes zero was shown, and the OFDM system for 5GHz band high-speed wireless LAN that used optimization SAW Chirp-Z transform that had the positive reverse-Fourier transform function as an application example was examined. The SAW Chirp-Z transform is the only method by which a long-lived handset can be achieved. |
