Time-Varying Frequency Fading Channel Tracking In OFDM-PLNC System, Using Kalman Filter
Physical-layer network coding (PLNC) has the ability to drastically improve the throughput of multi-source wireless communication systems. In this paper, we focus on the problem of channel tracking in a Decode-and-Forward (DF) OFDM PLNC system. We proposed a Kalman Filter-based algorithm for tracking the frequency/time fading channel in this system. Tracking of the channel is performed in the t...
متن کاملDiscrete Rayleigh fading channel modeling
Diverse methods that have been proposed to model Rayleigh fading channels will be explored in this tutorial. Preliminary concepts related to wireless communications channel modeling are identified before introducing the models. The first model presented is the finite state Markov channel model which is based on the side information given by the received signal to noise ratio. The Markovian vali...
متن کاملMlse Based Equalization and Fading Channel Modeling for Gsm
This paper presents an outline on the need of equalization in case of GSM systems. The modulation scheme employed in GSM systems is GMSK, which is both power and spectrum efficient, but at the cost of increased intersymbol interference. The effect of inter-symbol interference is more severe in case of multipath fading channel. This obviates the need of near optimum equalization. In this paper f...
متن کاملFilter Centered Nonisotropic Fading Channel Archetypal For Wireless System Assessment
In this paper filter based nonisotropic fading channel model for evaluating mobile radio communication is been proposed, fading occurs due to the multipath propagation of the signal. For assessing the performance and characteristics of a wireless communication system the channel has to be modelled in laboratory settings, the channel model can be hardware or software based. The development of th...
متن کاملDesign of Fading Channel Simulator Based on IIR Filter Using Genetic Algorithm
This article designs a Rayleigh fading channel simulator using IIR filter (called Doppler filter), which is used to approximate the Jakes Doppler spectrum. We mainly focus on the design of Doppler filter and model it as an optimization problem. Non-convexity of the problem is proved in this paper and genetic algorithm (GA) is used to optimize it, which has never been used before in this area. S...
