Reducing the Effects of Intersymbol Interference in Diffuse DPIM Optical Wireless Communications
This paper investigates the performance of digital pulse interval modulation (DPIM) in the presence of multipath propagation and additive white Gaussian noise. To combat intersymbol interference (ISI) guard slots and a non-linear equaliser have been introduced. The average optical power requirements (AOPR) due to ISI for cases with/without guard slots and with equaliser are analysed using a cei...
متن کاملCoded-DPIM for Non-Diffuse Indoor Optical Wireless Communications
Digital Pulse Interval Modulation (DPIM) technique coded using a 1/3 code rate convolutional codes with 3constraint length is presented. The channel model used is that of the non-diffuse environment with no multipath induced dispersion. Coding DPIM results in an improved packet error rate performance compared with uncoded DPIM but at the price of increased bandwidth requirement while maintainin...
متن کاملPerformance of the Wavelet Transform-Neural Network Based Receiver for DPIM in Diffuse Indoor Optical Wireless Links in Presence of Artificial Light Interference
Artificial neural network (ANN) has application in communication engineering in diverse areas such as channel equalization, channel modeling, error control code because of its capability of nonlinear processing, adaptability, and parallel processing. On the other hand, wavelet transform (WT) with both the time and the frequency resolution provides the exact representation of signal in both doma...
متن کاملThe Effect of Multipath Propagation on the Performance of DPIM on Diffuse Optical Wireless Communications
This paper investigates the performance of digital pulse interval modulation (DPIM) in the presence of multipath propagation and additive white Gaussian noise. The results for optical power requirements normalised to the average optical power required by the on-and-off keying (OOK) verses the channel normalised delay spread for DPIM without guard band and with guard bands are presented, and are...
متن کاملComparative study of classifiers to mitigate intersymbol interference in diffuse indoor optical wireless communication links
The maximum data rate that can be achieved in diffuse indoor optical wireless communication (OWC) is limited due to the effect of intersymbol interference (ISI). The adverse effect of ISI on the system
