Sample rate reduction in data communication receivers. Digital sampling of analog data is performed using a reduced sample rate. The reduction factor may be any number of factors including a factor that divides the sample rate by a factor of two. The reduction of the sampling frequency is from a sampling frequency that is greater than twice the highest frequency component in an analog input signal. These analog input signals may be I and Q streams in certain embodiments. A digital interpolation filter may be employed to increase (up-convert) the sample rate of a digital signal before it is input to a VID filter that is used to recover the transmitted symbols from the over-sampled data stream. In this embodiment, this technique allows a front end of a communication receiver to be clocked at a lower sampling rate without affecting the performance of the VID filter.
