Arduino Based Smart Bell
Abstract: In today’s era, many school/college bells are operated manually. But there is requirement of accuracy in operation. In schools/colleges, there are many digital clocks available with bells but they ring only at specific time and cannot stop after specific time. Here a new and inexpensive design is being presented. The Arduino uno is used for controlling all the functions, it gets the time through the keypad and stores it in …

Automatic Language Identification using Basic Signal Class
Abstract: Automatic language identification (ASLID) is a problem of identifying an unknown language from spoken utterance by a computer. A segmental approach to ASLID based on the assumption that the acoustic structure of languages can be estimated by segmenting speech into three basic classes of speech signals. This paper presents a procedure of ASLID with the details of methodology and the results without recognizing the words, but the lengths segments of …

Native Language Identification from Spoken Indian English
Abstract: Automatic speech recognition (ASR) systems that facilitate voice based search and information retrieval have gained importance recently. While the performance of ASR systems for Indian languages have improved in the recent past. They have yet to gain wide acceptability as much as the ASR systems for English spoken by Indians. Almost all Indians learn English as a second or third language. So, the phoneme set and the prosody of native …

Study of Multiple Input Multiple Output Free Space Optical Terrestrial Link
Abstract: AbstractAtmospheric turbulence causes mitigation in the performance of the Free Space Optical Link (FSO) transmission. The performance changes due to scintillation. To reduce the effect of scintillation, we have employed a Multiple Input Multiple Output (MIMO) FSO link which gives better performance as compared to Single Input Single Output (SISO) FSO link. We have combined the detector output with different combining techniques i.e. Selection Combining (SC), Equal Gain Combining (EGC) …

Comparative Analysis of Power Penalty versus Crosstalk in Optical Active Network Components like Erbium Doped Fiber Amplifier, Raman Amplifier and Semiconductor Optical Amplifier
Abstract: AbstractOptical amplifiers boost the power of optical system without optoelectronics (O-E-O) conversion. The optical amplification process is accompanied by Amplified Spontaneous Emission (ASE) noise that accumulates along the transmission line and degrades the optical signal to noise ratio (OSNR). Intensity modulation in one channel causes crosstalk in the other channel via the change of the complex refractive index in the amplifier. In this paper, authors tried to calculate and compare …

PAPR Reduction using Selective Mapping Method for OFDM Communication Systems
Abstract: AbstractSelective mapping method (SLM) is one of the most important techniques used for peak-to-average power ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) communication system. It is simple in implementation, gives distortionless transmission and reduces PAPR significantly. Mathematical modelling and Matlab simulation have been carried out to analyse its performances. At of CCDF, PAPR values for OFDM signal without applying any reduction technique is 11.5, 11.8, 12.1, 12.4 and …
