High-performance, high-throughput IEEE 802.11 DSSS WLAN via carrier-interferometry chip-shaping

WLAN (wireless local area networks) promise to combine the mobile connectivity of the wireless world with the speed and robustness of current wired systems. With IEEE 802.11, WLAN are emerging that support a variety of data types as well as rates. This paper introduces a novel carrier-interferometry chip-shaping filter to the DSSS implementation of IEEE 802.11 WLAN. This technique is capable of improving performance and doubling the throughput of the current DSSS system. It is shown that, at a bit error rate of 10/sup -3/, the proposed method gains 4 dB over the current DSSS WLAN while offering twice the throughput.
