ABSTRACT:
Systems and methods for digital signal averaging using parallel computation structures are disclosed herein. An exemplary method includes: receiving a series of samples in the time domain, each sample containing a number of bit positions M; averaging, using coefficient polynomial arithmetic, the value in a selected one of the bit positions in each of the samples to produce an average of the bit position, wherein the selected bit position remains constant during the averaging; and repeating the averaging for another selected bit position. Another exemplary method includes: receiving a series of samples in the time domain, each sample containing the same number predefined number of bit positions M; and for each bit position, averaging, using coefficient polynomial arithmetic, the value in the corresponding bit position in each of the samples to produce a plurality of averages, each average corresponding to one of the bit positions.
