On the other hand, digital filter banks find various good applications in communications signal processing.
Digital Nyquist pulse-shaping filtering is an important application of multirate filtering techniques to communications signal processing.
We contrast the communications and processing overheads of our scheme with those of flooding and pure tree-based broadcasting, using both analysis and simulations.
The current approaches still suffer from problems related to the energy consumption of mobile devices and overhead in terms of communications and processing.
Compressed sensing (CS) is a novel paradigm shift in sampling and signal acquisition which has attracted considerable attention for application in wireless communications, signal processing, and array processing [1 3].
State-of-the-art digital communications and signal processing techniques have caused a major resurgence in high frequency (HF) communication systems by reducing equipment size, improving communication reliability, and shortening the deployment time.
On the other hand, many applications in digital communications and multimedia processing exhibit enormous amounts of data-level parallelism (DLP).
Efficient transceiver design constitutes a perennial re- search topic in the communications and signal processing society, and recent years have seen increased interest on multiantenna and multiuser settings.
Toward this end, development of cost-efficient hardware architecture together with suitably designed channel estimation, beamforming, as well as other communications and signal processing techniques require much further research [77 83].
His research interests fall into the broad areas of communication theory, wireless communications, and statistical signal processing.
