Abstract

A communications terminal adapts to different operating standards by using software algorithms and digital processing instead of physically dedicated hardware. The communications terminal includes digital processing circuits (103) having a digital signal processor and microprocessor circuits, volatile and non-volatile memory, signal characteristics stored in memory and receiver circuitry to receive and digitize a radio signal. The communications terminal receives the radio signal, converts the radio signal into a digital signal and compares the signal characteristics of the digital signal to signal characteriscs of stored signals. The comparison of the signals identifies the standard of the radio signal and determines the format and protocol of the signal. The hardware is then reconfigured to operate according to the identified standard, format and protocol.
