摘要： A system and method for determining operating parameters to control a communication rate for an adaptive rate communication system includes a transmitter (101) to transmit a signal (135) through a network (142) to a receiver (103). The receiver (103) determines operating parameters based on, among other things, packet information from a received signal (e.g., packet). The receiver conveys the operating parameters to the transmitter for use in subsequent communications from the transmitter (101) to the receiver (103).

摘要： A system and method for determining operating parameters to control a communication rate for an adaptive rate communication system includes a transmitter (101) to transmit a signal (135) through a channel (142) to a receiver (103). The receiver (103) determines operating parameters based on, among other things, an effective bit rate and a percentage of speech in the signal. The receiver conveys the operating parameters to the transmitter for use in subsequent communications from the transmitter (101) to the receiver (103).

摘要： A method and system are provided for reducing power amplifier induced distortion. Power amplifier induced distortion is iteratively estimated and cancelled. When the difference between the current estimated power amplifier distortion and the previous estimated power amplifier distortion is less than a convergence threshold, particular M-QAM constellation points that are still in error are determined A M-QAM constellation point correction routine is provided that can move the incorrectly estimated M-QAM constellation points that are in error towards their expected quadrants by generating updated M-QAM constellation points. The remaining estimated non-linear power amplifier induced distortion in the received signal can then be estimated and canceled.

摘要： Apparatus are provided for a communication signal processing apparatus having a channel estimator configured to generate a first channel estimation at a first time point, a linear predictor coupled to the channel estimator, and an adaptive filter coupled with the linear predictor. The linear predictor is configured to predict a second channel estimation based on a second time point and a channel frequency. The second time point is concurrent or subsequent to the first time point. The second channel estimation includes a first coefficient. The linear predictor includes a first predictor having a sample time point. The first predictor is configured to generate the first coefficient of the second channel estimation based on the sample time point and the second time point. The sample time point is prior to the second time point. The adaptive filter is configured to recursively determine the second channel estimation.

摘要： A communication system is provided that includes a transmitter device and a receiver device. The transmitter device transmits input data as a transmitted signal having the known non-linear distortion (NLD) characteristic. The receiver receives a received signal that represents a channel affected version of the transmitted signal and that has the known NLD characteristic. The received signal includes power amplifier distortion (PAD) induced by the transmitter device's power amplifier. The receiver is designed to iteratively estimate, based on the known NLD characteristic, remaining PAD caused by the power amplifier, and to iteratively cancel estimated PAD to reduce PAD in the received signal.
