Optimized Companding Technique using Firefly Algorithm for PAPR Reduction in OFDM System
Abstract: AbstractThe current trends in wireless industry are based on multi-carrier transmission technique such as Orthogonal Frequency Division Multiplexing (OFDM) which provides high data rates and is highly immune to frequency selective fading. However, OFDM is handicapped with a major problem of high peak-to-average power ratio (PAPR), which gives rise to non-linear distortion, inter-symbol interference and out-of-band radiation. Several PAPR reduction techniques have been devised over the last few decades in …

Investigations on PAPR Reduction using PTS Technique for OFDM Communication Systems
Abstract: AbstractOrthogonal Frequency Division Multiplexing (OFDM) is a spectral efficient technique for high data rate communication systems. It also provides robustness to multipath frequency selective fading but suffers from high peak-to-average power ratio (PAPR) and causes high power amplifiers to operate in the nonlinear region. In this paper partial transmit sequence (PTS) as PAPR reduction technique has been investigated. Mathematical modelling and Matlab simulation have been carried out to analyse its …

Experimental Analysis of the Effect of Fine Milled Husk of Rice as a Novel Filtration Control Agent for Water Based Drilling Fluid System
Abstract: Drilling operation is a complex process that requires integration of various engineering systems. As the drilling continues, the formation encountered offers challenges to wellbore integrity as pressure increases with depth. The influx of formation fluid is contained by the overbalance provided by weighted drilling fluid column. Another critical function of the mud is to restrict the filtration fluid lost to the formation by forming a suitable mud-cake around the wellbore. …
