Abstract: The input (and output) power of a multi-carrier amplifier can be controlled to allow the amplifier to operate at high RF power levels and still remain within a power rating profile. The amplifier (or amplifiers) power is controlled using an aggregate scaling factor. The aggregate scaling factor is generated from a plurality of amplifier scaling factors. Each amplifier scaling factor is generated based on a comparison of a time-averaged total power and a corresponding threshold.

Abstract: The power level of at least one forward-link signal is determined for a measurement interval, where the measurement interval has a duration smaller than or equal to the time period in which at least one power-indicative signal characteristic can change. For example, a power-indicative signal characteristic used can be the information rate of the signal, which can change once per frame. In this case the measurement interval would be smaller than or equal to a frame. Preferably, the measurement interval is smaller than the time period in which any of the power-indicative signal characteristics can change. The power level of the signal is based on the signal's power-indicative signal characteristics during the measurement interval. In one embodiment of the invention, the signal's power-indicative signal characteristics include the information rate, and the gain of the signal.

Abstract: A DPRAM is placed in the RF path before the digital to analog converter, to provide dynamic path gain compensation to the digital signal prior to conversion to an analog signal. The DPRAM stores corrections to the signal to compensate for amplitude losses in the signal arising from heat and non-linearities. The DPRAM has two sets of identical addresses. A logic switch, alternately directs an input signal to one of the two sets of addresses. Pre-calculated signal values which compensate for path gain are stored in one of the two sets of addresses in the DPRAM. The signal input to the DPRAM is directed to the other block. The value of the signal input to the DPRAM will determine the address to which the new value can be found. It is this new value which is actually input to the DAC and from which an analog signal is created.

Abstract: Presented is a method for reducing the peak to average ratio where the signal is multiplied prior to digital to analog conversion and subsequently subject to the full scale of a digital to analog converter, disproportionably amplifying the average signal more than peak signals, reducing the ratio of the peak signal to the average signal.

Abstract: A method that adjusts the power level of a set of forward-link signals of a base station responsive to the loading of the forward link as determined by a power level measurement of the signal set. One power level measurement is a pilot fraction of the forward link. Other power level measurements, such as the signal set's power level, can be used, alone or in combination, instead of or in addition to the pilot fraction of the forward link to adjust the power level of the signal set. The power level of the signal set can be changed in any manner, including by scaling it by a scaling factor, or by increasing the power level by a fixed or a variable amount. The power level measurement of the signal set is obtained during a current time period. The scaling factor that will be used in the subsequent time period is determined using the power level measurement. In one embodiment of the invention, the scaling factor can be obtained from a look-up table that is based on the power level measurement.

Abstract: A method that initiates call blocking responsive to a call-quality measurement of the forward link. The call-quality measurement is a measurement of how well a mobile terminal is able to receive the forward link. One call-quality measurement is a pilot fraction of the forward link, which is a ratio of the pilot's power level to the power level of a set of forward-link signals of a base station. Call blocking is initiated when an average pilot fraction is below a pilot-fraction blocking threshold. The pilot's power level is obtained for a time period, and the signal set's power level is obtained for the same time period. The pilot fraction is determined for the time period, and then used to determine the average pilot fraction for the time period. The average pilot fraction for the current time period is based on a pilot fraction for the current time period, and an average pilot fraction for a previous time period.
