WebThis means that any strong echo must be conditioned so as to not saturate and distort the receive chain and any weak echo must be amplified while inducing minimal noise to determine the source of the echo. For this purpose, most of the receiver AFEs consists of: • A highly linear low noise amplifier (LNA) – whose gain is digitally programmable.

WebMay 30, 2016 · If you have a spot with loud and quiet passages – you whisper and then scream – you may have to “work the mic”. Move closer for the quiet parts and back for the loud parts. You don’t need to be extreme … WebThere exists a vast literature on acoustic echo cancellation for slowly-varying channels (see [4] for a survey). However, when a channel has a hidden but rapidly-varying gain factor, as can be the case in systems with Automatic Gain Control (AGC), this assumption is no longer valid and conventional methods apply quite poorly.
