摘要:An RF transmitter filter for use in a wireless communication system is disclosed.The filter includes a waveform detector to detect a power level of a transmitted datastream on a symbol-by-symbol basis. The filter also includes a processor to select acombination of filter parameter values according to the power level. The RF transmitter

filter selects and adjusts filter parameters (i.e., number of taps or filter length, wordlength, coefficient quantization, sampling rate, tap delay, sampling bits, etc.) based onsignal waveform characteristics. The adjustments limit the transmitted bandwidth andallow transmitted signals to meet an emission mask, while still enabling a receiver torecover the correct sample values of transmitted symbols. The filter further includes areconfigurable digital filter to filter the transmitted data stream according to thecombination of filter parameters.
