摘要：
A method and system for fractionally converting sample rates. Fractional rate conversion for a transmit path of a transceiver is achieved by upsampling an input signal having a first sample rate by a first integer factor, removing aliasing resulting from the upconversion process, and then downsampling the intermediate signal by a second integer factor to provide a final signal having a second sample rate. The first factor and the second factor are selected to obtain a desired output sample rate that is a fraction of the sample rate of the input signal.
