Abstract :
The paper deals with the design of an all digital multirate receiver with nonsynchronized IF-sampling and digital timing correction, that can be used in software defined radios. By performing timing correction prior to matched filtering, the complexity of the matched filter is reduced, but at the expense of additional aliasing. Design parameters, yielding low degradations with respect to synchronized baseband sampling, are provided.
