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 …

Study and Performance Analysis of Orthogonal Frequency Division Multiplexing with Different Modulation for Rayleigh Channel Model
Abstract: AbstractFor the advancement of wireless communication systems, methods such as MIMO, OFDM and integrating them together as MIMO-OFDM are very useful. OFDM is used in numerous wireless transmission standards nowadays. In OFDM, high rate data stream is divided into low-rate streams which are transmitted together over a number of subcarriers. A broadband and frequency-selective channel are transformed into a multiplicity of parallel narrow-band single channels by the OFDM modulation. By …

A Survey of Queuing and Scheduling Mechanism of Input-queued Switches
Abstract: ABSTRACTHigh-speed routers play an important role in the Internet. A main hindrance to high-speed router design is its switch architecture. It concerns with how packets are moved from switch input ports to output ports. The switch architecture can be classified as Output-Queued and Input-Queued switches. It is well known that Output-Queued switches can achieve optimal delay-throughput performance. Output-queued switches are generally impractical for high-speed implementation because of high speed needed …

Preliminary In Silico Analysis of Choline Monooxygenase and Betaine Aldehyde Dehydrogenase from Suaeda monoica Forssk. and its Expression in E. coli.
Abstract: AbstractIn a tropical country like India, the yield of crop plants is majorly affected by soil salinity and drought. One of the strategies to address this problem is by introducing genes responsible for salinity/drought tolerance in crop plants. Such genes could be identified and isolated from mangrove plants, as they are known to have evolved certain physiological mechanisms to augment saline environments. One such mechanism is the accumulation of Glycine …
