ABSTRACT:
MIMO receiver with a reconfigurable pooled digital filter is disclosed. A processor sets parameters of the filter to minimize the number of instructions per second and the amount of power required by the filter to perform, while matching the filter to a transmitter filter. The processor uses an algorithm or a lookup table stored in memory to select the combination of filter parameters. The parameters may be selected from at least one of: a number of taps, a filter length, a word length, a coefficient quantization, a sampling rate, bits per sample, a sampling bit, a tap delay and a coefficient length. After selecting a combination of filter parameters, the processor sends a control signal to the adaptive filter. The pooled adaptive filter reconfigures itself in accordance with the selected filter parameters.
