Multiple input multiple output (MIMO) transceiver with pooled adaptive digital filtering

摘要

A multiple input, multiple output (MIMO) transceiver includes a reconfigurable pooled digital filter. 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 at least one of: a transmitter filter and a receiver 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.
