Distributed Sparse Adaptive Algorithm for NonGaussian Noise Applications
The goal of this paper is to propose a distributed adaptive algorithm for estimation of sparse unknown parameters in the presence of nonGaussian noise. The proposed adaptive algorithm uses zero norm for accelerating the ...
A new filterbank-based complex CDMA system for transmission in underwater acoustic channels
In this paper a novel Alamouti-type coding scheme is
presented for the complex CDMA OFDM/OQAM system based
on Walsh-Hadamard (W-H) spreading codes. The proposed
scheme introduces an approach to gain ...
