Abstract :
This paper describes the software implementation of the baseband portion of a variable-rate modem. The modem can handle arbitrary symbol rates with a fixed input/output sample rate. This approach reduces hardware complexity related to external clock generation circuitry, offers complete flexibility in the selection of symbol rates, and conveniently accommodates symbol-timing and symbol-rate corrections.
