An Optimized SAW Chirp-Z Transform for OFDM Systems
Takaya Watanabe (World Technology Instrument Co., Ltd.) WBS2008-51
Abstract (in Japanese) (See Japanese page) 
(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 conversion processor composed of SAW Down Chirp Filter of bandwidth 100MHz and N=2048 becomes 5.5 GFLOPS. 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 conversion 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.
