Symmetric RBF classifier for nonlinear detection in multiple-antenna aided systems

, 2008
In this paper, we propose a powerful symmetric radial basis function (RBF) classifier for nonlinear detection in the so-called “overloaded” multiple-antenna-aided communication systems. By exploiting the inherent symmetry property of the optimal Bayesian

Sparse Array Design for Wideband Beamforming with Reduced Complexity in Tapped Delay-lines [PDF]

Sparse wideband array design for sensor location optimization is highly nonlinear and it is traditionally solved by genetic algorithms (GAs) or other similar optimization methods. This is an extremely time-consuming process and an optimum solution is not

Sparse beamforming for limited-backhaul network MIMO system via reweighted power minimization

, 2013
—This paper considers a downlink multicell coopera-tion model in which the base-stations (BSs) are connected to a central processor (CP) via rate-limited backhaul links.

Combined Beamforming and Space-Time Block Coding with Sparse Array Antennas

, 2002
We continue our investigation of joint beamforming and transmit diversity with space-time block coding. In particular, the performance of a four-element array antenna is considered, in the context of an indoor wireless communication system.

Aliasing-free wideband beamforming using sparse signal representation

, 2011
Sparse signal representation (SSR) is considered to be an appealing alternative to classical beamforming for direction-of-arrival (DOA) estimation. For wideband signals, the SSR-based approach constructs steering matrices, referred to as dictionaries in ...
