ABSTRACT:
The programmable modem for digital data of the present invention provides a highly programmable, digital modem implemented in an integrated circuit which can be customized to specific applications. The programmable modem uses spread spectrum techniques and is specifically programmable to alter the parameters of the modem to improve performance. The present invention also provides a systematic method and development kit to provide rapid customization of a modem for a particular application or for rapid specification of a high-performance application specific integrated circuit mode.
