• To study in detail the different types of FM transmitters & Receivers and PM Transmitters and Receivers
• To gain knowledge about different digital modulation techniques for digital transmission.
• To have knowledge about base band transmission ISI and distortion free base band transmission
• To know the spread spectrum modulation techniques and different multiple access methods.
1. SPECTRAL ANALYSIS AND RANDOM PROCESS 9
Spectral characteristics of periodic and aperiodic signal – Spectra of common signals related to communication – cross correlation – autocorrelation and power / energy density spectra – random signals and process – modelling noises.
2. ANALOG MODULATION SYSTEMS 9
Basic principles of AM, FM, and PM – Spectra – power consideration – receivers characteristics and deduction of AM, FM, and PM and Systems performance – Threshold effects reduction.
3. BASE BAND DATA COMMUNICATION 9
Sampling and quantisation – PCM, ADPCM, DM, ADM, Base band pulse shaping – binary data formats – base band transmission – ISI – correlative coding – optimum SNR – matched filter detection.
4. DIGITAL MODULATION 9
Digital modulation – coherent binary modulation techniques – coherent quadrature modulation techniques – non-coherent binary modulation – M-array modulation – performance of digital modulation systems based on probability if error – band width – ISI.
5. SPREAD SPECTRUM AND ERROR CORRECTION TECHNIQUES 9
Fundamental concepts – Direct sequence spread spectrums and frequency hopping spread spectrum – Block Codes – cyclic codes.
