  • Technique for performing an automatic channel search and switch during talk-time in mobile transceivers
    Patent number: 5867766
    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.
