A single-chip modem that uses digital signal processing (DSP) to perform the modem functions is described. The DSP modem is a complete single-chip modem which handles all of the popular international standards for frequency-shift keyed modems. These specifications include the Bell 103 and 202 specifications for North America, and the CCITT V.21 and V.23 specifications in Europe. The authors describe modem system aspects, the architecture and philosophy underlying the design of this modem, and some of the special features that are incorporated into the modem through the use of digital signal processing.
