Abstract
A universal modem has a software-configurable modulator/demodulator which accommodates different modulation formats such as those associated with terrestrial, cable, phone line, satellite and wireless communications to be transmitted and received through a single device in which the modem has reconfigurable logic to accommodate the format of the signals being received or transmitted. In one embodiment, the system tracks channel noise and changes modulation format at both the transmit and receive sides of the system through the use of a controller that controls both sides.
