This study analyses the impact of antenna correlation on orthogonal space–time block coding in amplify‐and‐forward cooperative relay networks in conjunction with different adaptive transmission techniques over Rayleigh fading channels. Closed‐form ...

Small cell networks enhance spectrum efficiency by handling the indoor traffic of mobile networks on a frequency‐reuse operation. Since most of the current mobile traffic happen in indoor, the authors introduce a prioritisation shift by imposing a ...

In this study, the authors develop a novel solution for hybrid global navigation satellite systems, differential navigation satellite systems and time of arrival cooperative positioning (CP) based on iterative finite difference particle filter (PF) in ...

This study investigates resource allocation problems for a point‐to‐point multi‐carrier multiple‐input multiple‐output cognitive radio network. Different from conventional resource optimisation problems, a joint power and bandwidth resource optimisation ...

In this study, the authors propose a continuous rate and power allocation algorithm for multiuser downlink multiple‐input–multiple‐output orthogonal frequency‐division multiplexing systems with coordinated multi‐point transmission. The optimisation ...

The authors recall the application of fixed‐lag particle smoothing (FLPS) to perform blind turbo equalisation under a Bayesian framework, assuming that the noise variance is unknown. This approach has been successfully applied in previous works, at the ...

Recent growing interest for location‐based services has created a demand on object localisation approaches with low cost and high accuracy. In this study, the problem of distributed multi‐object localisation using fingerprints of received signal strength (...

Max‐log‐maximum a posterior (MAP) detection is preferred in practical systems rather than log‐MAP because of its lower complexity, but also suffers from a considerable performance loss. In this study, the authors focus on the performance optimisation for (...

This study presents novel strategies to improve the decoding performance through base‐station cooperation. In the proposed schemes, the soft output of the demapper at a serving base station (SBS) is replaced by a combination of log‐likelihood ratio ...

In this study, the performance of different preamble‐based channel estimation techniques is analysed for orthogonal frequency division multiplexing/offset quadrature amplitude modulation (OFDM/OQAM) modulation systems. Three pilot allocation methods, the ...

Multitone‐frequency and quadrature‐amplitude modulation (MFQAM) is a combination of multitone frequency‐shift keying and quadrature‐amplitude modulation (QAM). In this study, the authors consider MFQAM with active subcarriers grouped in balance, where the ...

Two‐way relaying systems efficiently accomplish transmissions in both directions within dual‐hop, hence, two time slots can be saved compared with one‐way relaying. However, the conventional two‐way relaying protocol requires the assumption of symmetric ...

The split‐symbol moment estimation (SSME) algorithm is a conventional method to estimate the signal‐to‐noise ratio (SNR) in communication systems for M‐ary phase shift keying signals. However, the conventional SSME is based on the assumption of symmetric ...

The main factor to degrade the orthogonality of OFDM subcarriers is the carrier frequency offset (CFO) linked to the intercarrier interference problem. Hence, it is necessary to precisely estimate and suitably compensate the CFO. In this study, two pilot ...

In free space optical (FSO) communications, several factors can strongly affect the link quality. Among them, one of the most important impairments that can degrade the FSO link quality and its reliability – even under the clear sky conditions – consists ...
