  In Radio waves, the digital data can be transmitted using Burst number of data using OFDM technique. So only an OFDM Technique is called attractive modulation techniques. In this OFDM signal transmission having so many disadvantages, one of the ma... see more

The accurate definition of the found in literature baseband signals statistical characteristics (distribution, numerical results, peak-toaverageratio) in the multichannel systems with orthogonal frequency-division multiplexing (OFDM) is studied. Not stric... see more

This work proposes a solution to overcome the effect for one of the main drawbacks of these days’ wireless systems, where Multiple-Input Multiple-Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM) combinations has been used. High peak-to-aver... see more

This work proposes a new algorithm to enhance the performance of the speaker verification over the communication systems based Multiple-Input Multiple-Output (MIMO) - Orthogonal Frequency Division Multiplexing (OFDM) techniques. The algorithm mainly tack... see more

 This paper is on multi-carrier wireless communication system, focusing on the physical layer in such modulation system. Multi-Carrier MC system has received much attention in modern communication technology and is finding attractive applications. Th... see more

A modified alternative signal technique for reducing peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing systems employing offset quadrature amplitude modulation (OFDM-OQAM) is proposed. Lower PAPR reduces the complexity of di... see more

Non-contiguous orthogonal frequency division multiplexing (NC-OFDM) is a promising framework for wireless communication systems due to OFDM characteristics like the spectral bandwidth efficiency, robustness to frequency selective fading channels, etc. How... see more

World's about 80% of the energy consumption is sustained by the extraction offossil fuels, which consists of oil, coal and gas. Another non-renewable resourcethat is exploited by humans is subsoil minerals such as precious metals thatare mainly used in th... see more

Teknologi Orthogonal Frequency Division Multiplexing (OFDM) telah banyak diimplementasikan dalam komunikasi digital berkecepatan tinggi seperti Wireless Local Area Network (WLAN), Digital Audio Broadcasting (DAB), Digital Video Broadcasting... see more
