EC2311 COMMUNICATION ENGINEERING
AIM
To introduce the concepts of communication systems engineering using wire and
wireless medium
OBJECTIVES
To introduce different methods of analog communication and their significance
To introduce Digital Communication methods for high bit rate transmission
To introduce the concepts of source and line coding techniques for enhancing rating
of transmission of minimizing the errors in transmission.
To introduce MAC used in communication systems for enhancing the number of
users.
To introduce various media for digital communication
UNIT I ANALOG COMMUNICATION 9
AM – Frequency spectrum – vector representation – power relations – generation of AM
– DSB, DSB/SC, SSB, VSB AM Transmitter & Receiver; FM and PM – frequency
spectrum – power relations : NBFM & WBFM, Generation of FM and DM, Amstrong
method & Reactance modulations : FM & PM frequency.
UNIT II DIGITAL COMMUNICATION 9
Pulse modulations – concepts of sampling and sampling theormes, PAM, PWM, PPM,
PTM, quantization and coding : DCM, DM, slope overload error. ADM, DPCM, OOK
systems – ASK, FSK, PSK, BSK, QPSK, QAM, MSK, GMSK, applications of Data
communication.
UNIT III SOURCE CODES, LINE CODES & ERROR CONTROL (Qualitative only) 9
Primary communication – entropy, properties, BSC, BEC, source coding : Shaum, Fao,
Huffman coding : noiseless coding theorum, BW – SNR trade off codes: NRZ, RZ, AMI,
HDBP, ABQ, MBnB codes : Efficiency of transmissions, error control codes and
applications: convolutions & block codes.
UNIT IV MULTIPLE ACCESS TECHNIQUES 9
SS&MA techniques : FDMA, TDMA, CDMA, SDMA application in wire and wireless
communication : Advantages (merits) :
UNIT V SATELLITE, OPTICAL FIBER – POWERLINE, SCADA 9
Orbits : types of satellites : frequency used link establishment, MA techniques used in
satellite communication, earth station; aperture actuators used in satellite – Intelsat and
Insat: fibers – types: sources, detectors used, digital filters, optical link: power line
carrier communications: SCADA
