Abstract
Disclosed is a variable bitrate radio modem unit that includes a transmit section and a receive section that are linked through a host computer. In the transmit section, the host computer is connected to a data modulator equipped with a variable bitrate data generator which in turn is connected to a radio transmit modem. In the receive section, a radio receive modem is connected to a clock/data recovery circuit which in turn is connected to an error detection and correction circuit. The error detection and correction circuit is then connected to the host computer. A connection is established at a predetermined bitrate between two host computers of two individual radio modem units. While data is being transmitted back and forth, the error rate of the data being received is determined by the error detection circuit. If the error rate is larger than a predetermined rate, the bitrate of the radio transmit modem of the transmitting unit is reduced. Conversely, if the error rate is smaller than a second predetermined rate, the bitrate of the radio transmit modem of the transmitting unit is increased.
