Comparative Analysis of the Model of DVB-T Model Using Various Modulation Techniques 16 QAM & 64 QAM for the Primary Colors
Abstract: Computerized TV broadcasting is the spirit without bounds transmission. Progressions in advanced innovation, pressure in sound and video flagging and other flag handling systems' improvement lead to qualitative change in the field of digital/computerized TV. Usage of a coaxial link and through satellite and earthbound way, computerized transmission is made conceivable. Digitized TV would execute the convolution coding plan alongside OFDM adjustment strategy. The pressure is done and afterward the …

BER Performance Analysis for Digital Modulation Techniques in AWGN Channel of FSO Communication System with Low Attenuation Coefficient
Abstract: BER is a potential methodology for examining digital transmission systems by providing a measurable and useful indication of system performance. If the BER rises within limit then the system performance will be obviously satisfactory. The paper represents BER performance of FSO communication system for a few number of digital modulation techniques: BPSK, QPSK, 4-QAM and 16-QAM in AWGN channel by exploiting the Matlab simulated BER versus SNR graphs. The numerical …

Implementation of 16-Bit Qam Using Texas Instruments
Abstract: In this paper, an implementation of 16-bit QAM is performed where there is a high use of Digital Video Broadcasting Cable (DVB-C), as there is increase in the usage the bandwidth requirement for each user is mutually increasing. Due to this, there is spectral congestion caused and drastic improvements have been taken in the field of communications. QAM multilevel modulation can offer an attractive solution to current bandwidth restriction in …

Signal Transmission in Underwater Using Passive Time Reversal for Single and Multiuser
Abstract: This paper describes passive time reversal communications, which enables multiple users to send information simultaneously to the time reversal array. Experimental results at 3.5 kHz with a 1 kHz bandwidth demonstrate that as many as six users can transmit information over a 4 km range in a 120 m deep water using quaternary phase-shift keying (QPSK) modulation, achieving an aggregate data rate of 6 kb/s. Moreover, the same data rate …

The DVB-H Standard: Comparative Analysis of the Results Obtained for Various Modulation Techniques and Different Code Rates
Abstract: DVB-H happens to be the technical specification for the transmission of digital TV to mobile telephones and PDAs—handheld receivers. Published as a formal standard, DVB-H is a physical layer specification designed to facilitate the proficient delivery of IP-encapsulated data over terrestrial networks. The making of DVB-H, which is closely associated with DVB-T, also entailed modifications of some other DVB standards dealing with data broadcasting, service Information, etc. It can be …
