This paper deals with a demodulation technique for oversampled LoRa signal. The usual maximum likelihood (ML) based demodulation method for LoRa chirp spread spectrum (CSS) waveform is dedicated to signals sampled at Nyquist rate, whereas considering ...

This paper deals with multipath channel estimation and equalisation in low range (LoRa). It is suggested to take advantage of the cyclic property of the symbols in the LoRa frame preamble to obtain an interference-free version of the symbols in the ...

In this work, a comparative analysis is performed to study the bit error rate and error vector magnitude achieved with the least‐squares (LS), the minimum mean squared error (MSE), and the Kalman filter (KF) channel estimators when these are applied to ...

The interference between filtered multi‐tone (FMT) symbols exists and becomes conspicuous especially in frequency selective fading channel, like an underwater acoustic channel. This leads to the necessity of channel estimation and equalisation. In this ...

In order to improve the anti-interference capability of high-throughput communication and improve the communication quality in performing real-time reliability allocation of high-throughput communication channel in the strong interference environment, a ...

The authors consider a multi‐hop amplify‐and‐forward full‐duplex relay system. They take a signal flow graph approach for finding the input–output relationship using Mason's gain formula, and use this expression to compute the system outage probability ...

In this study, the authors investigate a distributed time‐reversal space‐time block coded (D‐TR‐STBC) system with amplify‐and‐forward full duplex relaying (FDR) over frequency‐selective channel. In the first, they present an FDR to use in a cooperative D‐...

Channel shortening is a necessary equalisation for mitigation of inter‐symbol and inter‐carrier interferences in multicarrier transceivers. Its purpose is to reduce the length of the impulse response of the channel. In this study, the authors present a ...

The first part of the paper provides an overview of urban rent recapture and equalization today and the application of Transfer Development Rights (TDR) mechanism. Below, in the second part, staring from the definition of spatial data infrastructure you ...

A equalisation method of a wireless Asynchronous Transfer Mode (ATM) communication channel using a Complex BiLinear Recurrent Neural Network (CBLRNN) is proposed in this paper. A Genetic Algorithm (GA) is used for the pruning process of the trained ...

We consider the transmission of a discrete data sequence via a communication channel that is subject to (additive) noise with a known upper bound on its magnitude but otherwise completely unrestricted behaviour. We provide a general recursive algorithm ...

An ad hoc network is a set of wireless mobile nodes that communally form a network without specific user administration or configuration. There are several scenarios that do not have an available network infrastructure and could benefit from the ...

The most important technical challenge for the realization of 4G mobile networks is twofold: (a) to overcome the highly frequency-selective fading channel and (b) to significantly reduce the transmit power from mobile terminals. Recently, it has been ...

In areas lacking pre-existing physical cable or telephone networks, WiMAX could allow broadband access that has previously been unavailable. However, the physical limitations of wireless medium still present a fundamental technical challenge to reliable ...

This paper addresses the problem of developing a least mean squares (LMS) style decision feedback equaliser algorithm for minimising bit error rate (BER) in impulsive noise environments characterised by the α-stable distribution. The development ...

A linear prefilter can be used to reduce the required complexity of a maximum likelihood sequence detector Viterbi algorithm (MLSD-VA) by shortening the overall channel and prefilter impulse response in dynamic communication systems. The combination of ...

The grey-scale histogram of an image has become important for image preprocessing methods. Histograms are employed in generating binary images (segmentation), data compression, image enhancement and elimination of inhomogeneous illumination. Even the co-...
