摘要： A method and system for closed loop power control in a wireless communication network. A received signal is despread. The signal power of the despread received signal is estimated. The noise power of the despread received signal is estimated. Estimating the noise power includes multiplying the despread received signal with an orthogonal noise code to cancel the received signal, accumulating the multiplied despread received signal over one frame and determining a signal-to-noise ratio of the received signal at least in part by dividing the estimated signal power by the estimated noise power. A reverse power control bit is determined based on the determined signal-to-noise ratio.

摘要： A plurality of base station transceiver subsystems determine whether to scale the forward link transmission power level and, if so, by what amount to control forward link transmission power level mismatch. The plurality of base stations transmit reverse link signal-to-noise ratio information and forward link transmission power levels for a specified transmission to the base station controller. The base station controller compares the reverse link signal-to-noise ratio readings received from each of the plurality of base stations to determine and select a dominant base station. The base station controller then transmits the dominant base station's forward link transmission power level for the specified transmission to each of the plurality of base stations that is communicating with the mobile station that is in hand-off. Each base station, accordingly, determines whether to scale its forward link transmission power level.

摘要： A forward link transmitter in a sectored cell includes a baseband processor having traditional baseband signal digital processing circuitry in addition to including a digital hybrid matrix (vector and delay compensated transformation module) whose phase and amplitude (vector) and delay may be adjusted to compensate for downstream errors that are introduced and detected by a feedback circuit. Accordingly, the baseband processor, by monitoring an output of an analog hybrid matrix producing modulated and amplified radio frequency (RF) signals just prior to propagation from an antenna, can determine errors produced by the analog circuitry including the analog hybrid matrix and may compensate for the same by introducing an amplitude, phase and delay adjustment (in the digital domain) into output digital waveform signals to compensate for the error introduced downstream to the baseband processor.

摘要： A peak power regulator is disclosed that functions within a Code Division Multiple Access (CDMA) transmitter to reduce peak power spikes within baseband signals, controlling the out-of-band emissions, and maintaining the in-band signal quality within an acceptable degradation. In-phase and quadrature baseband signals are input to an envelope magnitude predictor within the peak power regulator. The envelope magnitude predictor outputs an estimate for the magnitude of the envelope that will be generated when the inputted baseband signals are modulated. This estimate is input to a multiplier that generates a ration by dividing the estimate by a maximum acceptable envelope magnitude. The ratio is subsequently input to a mapping table that outputs a scaling factor sufficient for reducing peak power spikes. The scaling factor is subsequently subtracted from a value of one and multiplied by first delayed versions of the in-phase and quadrature baseband input signals. The outputs from these multiplication operations, after being filtered within lowpass filters to remove out-of-band emissions caused by the operations, are referred to as excess power correction signals. These excess power correction signals are then subtracted from second delayed versions of the in-phase and quadrature baseband input signals to generate in-phase and quadrature baseband output signals.
