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 ...

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 ...

Multiple-input multiple-output (MIMO) system using orthogonal frequency division multiplexing (OFDM) technique has become a promising method for reliable high data-rate wireless transmission system in which the channel ...

Localization is one of the fundamental tasks in underwater acoustic sensor network (UASN) which is a challenging issue due to inhomogeneity and bandwidth limitation of underwater medium. Time of flight (TOF) and received ...

Abstract—The idea of adaptive state allocation (ASA) algorithm

is used in this paper to substantially reduce the computational com-

plexity of the maximum-likelihood sequence detection and estima-

tion ...

در این مقاله یک روش نوبت‌بندی برای سیستم MIMO-OFDMA در ارسال فراسو ارایه می‌گردد. معیار نوبت بندی، بیشینه سازی مجموع نرخ کاربران تحت قید محدودیت توان ارسالی هر کاربر می‌باشد. الگوریتم نوبت بندی پیشنهادی، با انتخاب زیرحامل ...

A new low-complexity Maximum Likelihood (ML) based detection scheme is presented in this paper for full-rate Quasi Orthogonal Space Time Block Code (QOSTBC) in Multi-Input Multi-Output (MIMO) systems with four-transmit ...

This paper presents the adaptive state allocation

(ASA) algorithm, a new scheme based on maximum likelihood

sequence detection (MLSD) of signals transmitted over Rayleigh

fading channels. Although MLSD ...
