Bayesian decision feedback equaliser for overcoming co-channel interference

Fast Blind Equalisation Based on a Bayesian Decision Feedback Equaliser

mined by the thermal distribution. With increasing temperature, the broadening of the distribution function increases. In addition, the spectrum shifts to longer wavelengths due to the temperature dependence of the bandgap. The magnitude of the emission decreases with increasing temperature due to the dominance of nonradiative recombination processes. We also measured the temperature dependence...

Minimum-SER linear-combiner decision feedback equaliser

The paper considers the conventional decision feedback equaliser (DFE) that employs a linear combination of the channel observations and past decisions. An expression of the symbol error rate (SER) is derived for the linear-combiner DFE with the general M-PAM constellation by utilising a geometric translation property of decision feedback. A method is developed to optimise the coefficients of t...

Multi-Input Multi-Output MLP/BP-based Decision Feedback Equalizers for Overcoming Intersymbol Interference and Co-Channel Interference in Band-Limited Channels

This paper presents a multi-input multi-output (MIMO) multi-layered perceptron neural network with backpropagation algorithm (MLP/BP). The proposal is a waveform equalizer for distorted nonreturn-to-zero (NRZ) data recovery in band-limited channels with co-channel interference (CCI). From the simulation results, we note that the proposed design can recover severe distorted NRZ data as well as s...

Start-Up Behaviour Of A Neural Network Assisted Decision Feedback Equaliser In A Two-Path Channel

Co-Channel Interference

This paper studies the problem of centralized dynamic channel assignment (DCA) in wireless cellular systems under space and time-varying channel demand. The objective is to minimize the number of channels required to satisfy demand while also satisfying cochannel interference constraints. Cumulative co-channel interference constraints govern channel reuse, via a threshold decision criterion bas...
