Beschreibung
Zusammenfassung:	The invention is a CDMA transmission control technology that includes various combinations of the following functionality: decresting, in-band to out-of-band ratio (RIO), power control, and spectral shaping. Decresting reduces peaks in the CDMA signal. RIO generates a ratio based on the signal strength of in-band versus out-of-band portions of the CDMA signal. Power control adjusts the gain of the CDMA signal based on quadrature signal calculations. Spectral shaping attenuates in-band portions of the CDMA signal adjacent to the corner frequencies. The CDMA transmission control technology can be implemented in a CDMA base station to extend range and capacity.
