摘要： Embodiments of a method and apparatus for selecting coefficients of a non-linear filter are disclosed. The non-linear filter receives a transmit signal and generates a non-linear replica signal of a transmit DAC of a transceiver. The method include applying a plurality of periodic test pattern signals to inputs of the transmit DAC, wherein the periodic test pattern signals include a stream of symbols. Receive symbols are collected at an output of a receiver ADC of the transceiver resulting from the plurality of periodic test pattern signals. A non-linear map is generated that provides a value for each of n consecutive symbols input to the transmit DAC. Coefficients of the non-linear filter are selected based on the non-linear map.

摘要： A device and method of high-speed transmission is disclosed. The method includes computing a signal quality of a received signal, the received signal being transmitted with a modulation order required by a default transmission modulation format. The signal quality is compared with a signal quality threshold required of the default transmission modulation format. If the signal quality is below the signal quality threshold, an indication of a level of signal quality failure is provided to a transmitter. The transmitter sets a number of un-coded bits within the transmission signal based upon the level of signal quality failure.

摘要： A wireless link between a first transmitter and a first receiver in a multiple access communications system is evaluated by receiving, at the first transmitter, information that is intended for a second receiver and that is transmitted in a second transmission mode that is different from the current transmission mode and obtaining an error measure for the information that is received at the first receiver and intended for the second receiver. The obtained error measure is then used to determine if the second transmission mode is an acceptable transmission mode. In an embodiment, if the second transmission mode is determined to be acceptable, then the current transmission mode of the first receiver can be replaced by the second transmission mode. In an embodiment, the current transmission mode is replaced by the second transmission mode only if the second transmission mode is a “higher” transmission mode than the current transmission.

摘要： The present inventions provide methods and systems for reducing the peak to average power ratio of a multi-carrier signal. Reducing the peak to average power ratio of a signal ensures that amplifiers and transmitters are not saturated, causing loss of data. Further, reducing peak to average power ratios reduces the consumption of power during transmission. Peak to average power ratios are reduced by applying a peak reduction signal component to one or more of the plurality of information signals that make up the multi-carrier signal. In one embodiment the peak reduction signal is a basis function of the communication system. The information signal is mapped to duplicate constellation points, which may be easily decoded by a receiver by performing a modulo operation. Negation of the peaks may be performed iteratively to remove any peaks produced during prior peak reduction operations.
