Syllabus: Basic blocks of a communication system: transmitter, channel and receiver; review of Fourier transforms, baseband and passband signals and their representations; Continuous wave (CW) modulation and demodulation: amplitude modulation (AM) - double sideband (DSB), double sideband suppressed carrier (DSBSC), single sideband suppressed carrier (SSBSC) and vestigial sideband (VSB) modulation; Angle modulation - phase modulation (PM) and frequency modulation (FM); narrow and wideband FM; Pulse modulation: sampling process; pulse amplitude modulation (PAM); pulse width modulation (PWM); pulse position modulation (PPM); pulse code modulation (PCM); line coding; differential pulse code modulation; delta modulation; adaptive delta modulation; Review of wide sense stationary (WSS) random processes: autocorrelation and cross-correlation functions, power spectral density, WSS processes and linear time invariant (LTI) systems, white Gaussian noise; Noise in CW and pulse modulation systems: Receiver model; signal to noise ratio (SNR); noise figure; noise temperature; noise in DSB-SC, SSB, AM and FM receivers; pre-emphasis and de-emphasis, noise consideration in PAM and PCM systems; Basic digital modulation schemes: phase shift keying (PSK), amplitude shift keying (ASK), frequency shift keying (FSK), and quadrature amplitude modulation (QAM); coherent demodulation and detection; signal space representation; Probability of error in PSK, ASK, FSK and QAM schemes; Multiplexing schemes: frequency division multiplexing; time division multiplexing.
