simulation of the QAM modulator in MATLAB‚ 1) Generation of random binary sequence‚ this is the input which is to be modulated. 2) Assigning group of 4 bits to each 16-QAM constellation symbol per the Gray mapping 3) Addition of white Gaussian Noise 4) Demodulation of 16-QAM symbols Upon reception of the signal‚ the demodulator examines the received symbol‚ which may have been corrupted by the channel or the receiver (e.g. additive white Gaussian noise). It selects‚ as its estimate of what was actually transmitted

Encoding methods and Modulation schemes 25.P.1 Computers use digital signalling‚ digitals signals are represented by the base 2 numbering system “Binary”. Binary bits are shown as 1 or 0‚ where 1 means ON and 0 means OFF. In a network where digital devices exist‚ digital signalling will be used. Dependant upon the encoding method used‚ a high voltage on a communications medium can represent a logical 1 and a low voltage of can represent a logical 0. Different methods of encoding exist these

EC51-DIGITAL COMMUNICATION UNIT-1 DIGITAL COMMUNICATION SYSTEM 1. What are the advantages of digital transmission? The advantage of digital transmission over analog transmission is noise immunity. Digital pulses are less susceptible than analog signals to variations caused by noise. Digital signals are better suited to processing and multiplexing than analog signals. Digital transmission systems are more noise resistant than the analog transmission systems. Digital systems are better suited to evaluate

ELECTRONIC COMMUNICATIONS SYSTEMS Wayne Tomasi‚ 5th edition Introduction to Electronic Communications Electricity began in 1837 when Samuel Finley Breese Morse invented the first workable telegraph. In 1894‚ Marchese Guglielmo Marconi successfully transmitted the first wireless radio signals through Earth’s atmosphere. In 1906‚ Lee DeForest invented the triode vacuum tube. Commercial radio broadcasting began in 1920 when radio station KDKA began broadcasting amplitude-modulated
