| Abstract(in English) | The OFDM system that can use it combined to the Fourier transform to the OFDM signal for amount of wave of the inverse Fourier transform and received OFDM can have a definite advantage in power consumption, a super-high-speed operation processing performance be possessed, and the SAW Chirp-Z transform be applied to high-speed wireless LAN and WAN. As for the SAW Chirp-Z transform, operation speed 5.5 GFLOPS is feasible in OFDM for 5GHz band high-speed wireless LAN. However, the following points exist as a problem to the OFDM system that consists of the SAW Chirp-Z transform. 1. The advantage of the power saving assumed to be an aim might decrease because the power saving of the Digital signal processing is also advanced. 2. There might be a limit in the adjustment of the chirp rate by the accuracy of the pattern of the SAW element. 3. In the SAW element, is not the temperature delay characteristic a problem? In this report, the solution of these various problems is presented. |
