    摘要： A system, method and computer program product that uses an expected output power level to compensate for slowly changing unintentional power fluctuations in a signal transmission system such that the actual transmitted power matches a calculated desired transmit power. Digital expected power data is sampled and filtered to generate an expected output power level. Actual output data is sampled and filtered to generate an actual output power level. A comparator periodically compares the expected output power level to the actual output power level. Preferably, the comparator first removes a correction value from the actual output power level that was added to the transmit signal to correct for unintentional power fluctuations. The resultant ratio or difference is sent to a correction module which generates a correction value therefrom. The correction value is converted to a dB quantity and added to existing correction values.

    摘要： A method for Automatic Gain Control (AGC) in a receiver is performed by a circuit having an inner loop and an outer loop. The method includes performing an outer loop energy detection, mitigating interference using the outer loop energy detection, and performing a frequency domain energy measurement in the inner loop. The method also includes adjusting a digital gain component in the inner loop and an analog gain component in the outer loop in response to the frequency domain energy measurement.

    摘要： A finite impulse response filter including a first circuit for providing plural delayed signals in response to an input signal. A second circuit is included for multiplying respective ones of the delayed signals by a corresponding coefficient and providing a respective intermediate signal in response thereto. A third circuit selectively changes the sign of respective ones of a first set of the intermediate output signals to provide a set of component in-phase signals. A fourth circuit selectively changes the sign of respective ones of a second set of the intermediate output signals to provide a set of component quadrature signals. The component in-phase signals are combined to provide an in-phase output signal and the component quadrature signals are combined to provide a quadrature output signal. In the illustrative implementation, the coefficients are generated in accordance with an industry standard via a storage device such as a register bank. The third and fourth circuits are controlled by a pseudo-noise sequence generator. The inventive implementation affords a considerable degree of efficiency in design in that in-phase and quadrature filter outputs are generated from a single filter thereby obviating the need for a second filter required by conventional teachings.

    摘要： In a code division multiple access communication system, a method and apparatus provide for an efficient testing of operating behavior of a quality indicator bit. The method and the accompanying apparatus include configuring a receiver to expect to receive a communication channel at a full data rate, and transmitting a signal from a transmitter to the receiver. The signal is carrying the communication channel at a data rate other than said full data rate, and at a power level for receiving at the full data rate. Consequently, the receiver fails to receive the communication channel at the full data rate. A received signal to noise ratio of the received signal at the receiver is determined. A value of the quality indicator bit is determined based on the determined signal to noise ratio. The determined value of the quality indicator bit is communicated to the transmitter.
