Abstract
A digital cordless telephone (10) includes a handset (12) and a base station (14). A voice activity detector (20) in the handset (12) determines whether speech or silence is being received by a microphone (13) in the handset (12). An active enable signal is transmitted to the base station (14) when silence is being transmitted. An adaptive comfort noise generator (30) in the base station (14) then provides a comfort noise to a destination telephone instead of the silence. The output level of the comfort noise is a function of an energy level of a linear data signal received by the base station (14) before the enable signal becomes active.
