Over a doubly selective channel, broadband transmission systems face challenges in
channel estimation and equalization. High mobility causes inter-carrier interference (ICI) …

Transmission over wireless channels can lead to intersymbol interference (ISI) as well as
interchannel (or intercarrier) interference (ICI). To decrease the results of ICI, this paper …

Abstract Filter Bank Multi-Carrier (FBMC) modulation has been recognized as a consistent
contender and a possible successor for Orthogonal Frequency Division Multiplexing (OFDM) …

A channel estimation scheme for a multi-input multi-output orthogonal frequency division
multiplexing (MIMO-OFDM) system was presented. The scheme makes use of the pilots to …

In this paper we study the effects of practical pilot-assisted channel state estimation on the
achievable information theoretic data rates (uplink and downlink) in a multiple antenna …

High data transmission rates and high mobility give rise to time-and frequency-selectivity in
wireless communication channels. This paper investigated time and frequency doubly …

In this paper, we study ARQ feedback in the context of two-way wireless communications. In
particular, we consider two nodes which wish to exchange data over a frequency division …

For OFDM system, we proposed a channel estimation method based on radial basis function
neural network (RBFNN). The neural network with Gaussian basis function is established …

In this paper, we propose a modified Alamouti code matrix and it associated with zero
padding orthogonal frequency division multiplexing known as (Alamouti-ZP OFDM). Which …

In the wireless communication system, the traditional single model channel estimation
method cannot tack the complex variability of the doubly selective channels. To solve this …
