Abstract
A digital signal, x(n) (where n is an integer), is decimated by determining a signal vector, y(k), of size M by partitioning samples of the digital signal, x(n) according to sampling phases of the samples. The signal vector, y(k), is projected onto an N-dimensional sub-space, wherein N is an integer and N<M. Where the digital signal is generated by means of oversampling, it is possible to perform decimation in a way that optimizes the signal-to-noise ratio (SNR) of the decimated signal by suitably determining the sub-space onto which the signal vector will be projected.
