Abstract :
The concept of soft clipping control is applied to the class of blind QAM receivers. This approach performs real time optimisation of the receiver´s quantization dynamic range and guarantees in a deterministic way a desired level of reliability for the soft signal clipping condition. Steady state and transient performance analysis provide effective insight on the proposed path-gain control technique, which is further evaluated by means of computer simulation.
