... scheme for two different normalized Doppler frequencies of 3.25 x (at 13.3ds) and 2.17 x 1OP6(at 0.89m/s), where the modem mode switching thresholds were set according to Table 4.8. The ... normalized Doppler frequencies of 3.25 x lop5 (at a vehicular speed of 13.3ds) and 2.17 x 1OP6(at a vehicular speed of 0.89ds). Further comparisons were made between the performance...

... complexity, adaptive receiver structures have been pro- posed [379]. An excellent summary of these adaptive receivers has been provided by Wood- ward and Vucetic [380]. Several adaptive algorithms ... scheme. Another adaptive system was proposed by Tateesh, Atungsiri and Kondoz [79], where the rates of the speech and chan- nel codecs were varied adaptively [79]. In their ad...

... 9. RBF-EQUALIZED ADAPTIVE MODULATION in a four-mode adaptive PSK scheme did not achieved a better performance across the 1 BPS throughput range. Instead, this four-mode adaptive PSK scheme ... for the adaptive scheme and the BPSK scheme, the mean BPS for the adaptive scheme improved by a factor of 1 S, resulting in a mean BPS of 1.5. In the SNR range of 9dB to 16dB, t...
