Compatible FBPSK , 2 . 4 GHz measurements demonstrate 4000 / 0 advantage , 24 dBm output power instead of

FBPSK, a new modulation technique which leads to nonlinear amplified BPSK modems is presented This BPSK compatible modulation takes advantage of the nonlinear processor pulse shaper FQPSK(1-4}. Nonlinearly amplified FBPSK have been shown to meet the IEEE 802.11 specifications for wireless LAN for Direct Sequence Spread Spectrum (DSSS) . Experimental data using the latest in microwave technology has shown that FBPSK provides 6.5 dB power advantage over conventional BPSK modems with about 0.3 to 1.1 dB depending on the chosen filters in both transmit and receive side .. FBPSK modulator can deliver 1 Watt output compared to 150 m Watt for BPSK, and can be demodulated using conventional BPSK demodulator. BER performance of FBPSK in both A WGN and Rayleigh fading channels has been evaluated and compared with conventional BPSK modems in both linear and nonlinear channels.
