Systems and methods for memory efficient signal and noise estimation

Abstract

Various embodiments of the present invention provide systems and methods for estimating signal and noise powers in a received signal set. For example, one embodiment of the present invention provides a method for determining signal power and noise power. The method uses a storage medium that includes a N×Ndata pattern. The N×Ndata pattern includes Nbits repeated Ntimes. Both Nand Nare each greater than one. The methods further include performing an initial read of the N×Ndata pattern, which is stored to a first register. Nsubsequent reads of the N×Ndata pattern are each processed by: performing a subsequent read of the N×Ndata pattern, and performing a difference calculation using the initial read of the N×Ndata pattern and the subsequent read of the N×Ndata pattern and resulting in the calculation of a difference vector that is stored to a second register; and performing a difference accumulation calculation to generate an accumulation vector which is stored to a third register. Based at least in part on the stored N×Ndata pattern and the stored difference vector, an electronics noise power is calculated.
