ABSTRACT:
A transceiver system having a base unit and a handset for communicating over a number of communication channels that are automatically switched during talk-time. A received-signal-strength-indicator (RSSI) circuit connects to the receiver for measuring the average energy received by the receiver over a baseband frequency bandwidth. The average energy includes the information, interference and noise portions of the received energy. The RSSI circuit transmits an RSSI output when the average energy exceeds a predetermined RSSI threshold. A discriminator-interference-and-noise-energy (DINE) circuit connects to the receiver for measuring out-of-band energy received by the receiver which is above the baseband frequency bandwidth. The out-of-band energy primarily comprises interference and noise energy. The DINE threshold detector provides a DINE output when the out-of-band energy exceeds a predetermined DINE threshold. A microcontroller connects to the RSSI and DINE circuits for monitoring, in real time, the RSSI and DINE outputs to detect the appearance of an interferer on the currently used communication channel. When an interferer is detected, the carrier frequency is automatically switched to a clean communication channel.
