Abstract :
Programmable transceivers are essential for efficient implementation of communication systems. This calls for implementation of various flexible signal processing blocks in the physical layer of a network. Rate conversion is an important functional block in programmable digital modems. In this paper, the implementation of an asynchronous interpolator for a digital modem is discussed and performances of three different types of interpolation filters are compared.
