Mitigation of interference on digital voice channels
First Claim
1. In a digital voice communication system, a method comprising the steps of:
- checking a channel for activity;
if activity is not detected on the channel, transmitting the at least one voice frame on the channel; and
if activity is detected on the channel, temporarily buffering at least one voice frame;
waiting a period of time prior to re-checking the channel for activity; and
if activity is still detected on the channel, repeating the step of waiting until activity is no longer detected on the channel;
otherwise, transmitting the at least one voice frame that was temporarily buffered on the channel.

Abstract
In a digital voice communication system, a transmitting radio (100/102) checks for activity on a channel. If activity is not detected on the channel, the transmitting radio transmits at least one voice frame on the channel. If activity is detected on the channel, the transmitting radio temporarily buffers the at least one voice frame and waits a period of time prior to re-checking the channel for activity. If activity is still detected on the channel, the transmitting radio repeats the step of waiting until activity is no longer detected on the channel; otherwise, the transmitting radio transmits the at least one voice frame that was temporarily buffered.
