Flat fading channel envelope prediction and equalization

摘要: Fading envelopes generated under constant velocity and acceleration conditions, modeling mobile communication scenarios, are predicted with a time-varying recursive linear predictor. The envelope prediction is used in an automatic gain controller the idea of compensating for amplitude distortion flat fading channel. Assuming that difference between phase distortions two consecutive symbols very small, effect removed using differential modulation scheme. Simulations show that, compensation, highly bandwidth efficient schemes such as QAM can be even environment.
