This project aims to strengthen the technical and scientific expertise within the partner institutions on adaptive compressive sensing and sparsity-aware techniques and their applications for wireless Communications, system Identification, array signal processing and distributed signal processing in wireless sensor networks. We will develop and investigate novel algorithms for compressive sensing that can exploit the sparsity in signals, resulting in improved performance and/or reduced complexity in a number of applications. We will also study the fundamental limits of the proposed algorithms and consider the derivation of analytical formulas to help in the design of practical algorithms. The proposed algorithms will be applied to problems that occur in electronic and wireless Communications systems. The project will set up a stronger collaboration between the two groups, aiming at 1) increasing the transfer of know-how and research tools and 2) producing joint publications. This proposal continues a collaboration initiated years ago during visits of the Brazilian team to the UK and of the British team to Brazil. (AU)
