Communication efficiency is of importance for wireless federated learning systems. In this paper, we propose a communication-efficient strategy over multiple-input multiple-output (MIMO) multiple access channels (MACs). The proposed comprises two components. When sending locally computed gradient, each device compresses high dimensional local gradient to lower-dimensional vectors using block sp...
Stereophonic acoustic echo cancellation is one of the expanding areas in the field of the speech/multimedia communication systems. In a conventional stereophonic acoustic echo canceller, working in a stereo communication system, the existence of the strong cross-correlation between the input signals to the two channels has the problem of the low convergence speed of the weights of the adaptive ...

Therefore, technological learning process in JRDs is conducted by using theme an...
Modern mobile communication systems are designed based on the cellular principle. The efficiency of such systems is primarily limited by interference from neighboring base stations at the cell edge. In recent years various schemes have been developed to minimize interference through base station cooperation. One such promising scheme is interference alignment (IA). Although theoretically well u...
