Abstract
A signal activity detector (SAD) receives, from a hangover addition unit of a different SAD, a final decision signal of the different SAD. The final decision signal indicates a final decision of the different SAD as to whether or not the different SAD detects activity in a received input signal. The SAD combines the final decision signal of the different SAD with a preliminary decision signal of the SAD and sends a result of the combining to a hangover addition unit of the SAD. The preliminary decision signal of the SAD indicates a preliminary decision of the SAD as to whether or not the SAD detects activity in the input signal. The hangover addition unit of the SAD generates a final decision signal of the SAD based on the result of the combining.
