Abstract: The invention is a CDMA transmission control technology (600) that includes various combinations of the following functionality: decresting, in-band to out-of-band ratio (RIO), (611) power control, and spectral shaping (614). Decresting reduces peaks in the CDMA signal. RIO (612) generates a ratio bas ed 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 quadratur e signal calculations. Spectral shaping attenuates in-band portions of the CDM A signal adjacent to the corner frequencies. The CDMA transmission control technology can be implemented in a CDMA base station to extend range and capacity.

Abstract: The invention is CDMA quadrature signal technology that controls the transmit power of a CDMA signal. The CDMA quadrature signal technology receives a CDMA signal, and in response, process quadrature components of the CDMA signal to generate a power control signal. The CDMA quadrature signal technology adjusts the gain of the CDMA signal in response to the power control signal. A CDMA transmitter transmits the CDMA signal after the gain is adjusted. One example of the CDMA transmitter is a CDMA base station. Using the invention, a multi-sector CDMA base station can control power without transferring gain information to base station components for all sectors. The invention eliminates unnecessary data transfer and storage.

Abstract: The invention is a CDMA signal transmission control technology (316). A CDMA (307) signal is transmitted that has in-band components and out-of-band components. Transmit control logic (316) automatically generates a ratio of signal strength of the in-band components versus the out-of-band components. In some embodiments of the invention, control logic (436) generates a transmit power metric signal based on the ratio. In other embodiments of the invention, control logic (436) determines excess forward link capacity based on the ratio. The CDMA signal transmission control technology (166) can be implemented in a CDMA base station (312).

Abstract: The invention is a CDMA decresting technology that reduces or eliminates peaks in the CDMA signal. The CDMA technology generates a correction signal in response to peaks in the CDMA signal that exceed a value. The value typically corresponds to the maximum power level of a power amplifier. The CDMA technology combines the correction signal with the CDMA signal to generate a decrested CDMA signal with reduced peaks. In some examples of the invention, the CDMA technology processes polar coordinate representations of the quadrature components of the CDMA signal to generate the correction signal. Using the invention, the power amplifier in a CDMA base station can operate at increased power levels without exceeding out-of-band signal power limitations. As a result, the base station operates more efficiently and with a greater range or capacity.

The CDMA technology combines the correction signal with the CDMA signal to generate a decrested CDMA signal (515) with reduced peaks. In some examples of the invention, the CDMA technology processes polar coordinate representations of the quadrature components of the CDMA signal to generate the correction signal. Using the invention, the power amplifier (625) in a CDMA base statio n can (512) operate at increased power levels without exceeding out-of-band signal power limitations. As a result, the base station operates more efficiently and with a greater range or capacity.

Abstract: Techniques for generating reference signals for multiple communication systems are described. An apparatus comprises a reference oscillator, a frequency control unit, and a plurality of frequency synthesizers. The reference oscillator generates a main reference signal and may be a crystal oscillator or some other type of oscillator. The frequency control unit estimates the frequency error of the main reference signal and provides a frequency error estimate. The plurality of frequency synthesizers receive the main reference signal and generate a plurality of system reference signals for a plurality of systems. At least one (e.g., each) frequency synthesizer corrects the frequency error of the main reference signal based on the frequency error estimate from the frequency control unit. Each frequency synthesizer may include a sigma-delta modulator used to generate a divider control for a phase locked loop (PLL). The divider control corrects for the frequency error of the main reference signal.
