摘要：
We report on the design and performance of a SAW based spread spectrum wireless LAN system which operates in the ISM band at 2.45 GHz. System IF frequency, transmission bandwidth and data rate are 348.8 MHz, 80 MHz, and 2 Mbit/s, respectively. Due to the high processing gain of 22 dB - made possible by the use of SAW devices - and the large transmission bandwidth the system is insensitive against narrowband fading and noise. We give a brief system overview and present measurements of the data throughput. Comparison with simulation results focused primarily on measured and modeled channel characteristics will also be presented.
