## 3 The Generalized AP-HSIC Algorithm for QAM Modulations
We also intend to develop techniques (based on Machine Learning) to estimate the channels between the transmitter and the receiver and evaluate the channels between the interference and the receiver, including identifying and classifying the interference or jamming. Our overall aim is to produce optimal feedback that offsets interference and increases the channel capacity and reliability under the same concept of optimal feedback.
