Communication Systems - I

Analysis tools such as Fourier series Fourier transforms signals systems and spectral densities are discussed in the second chapter. Introduction is presented in the first chapter.Third chapter presents additional analysis techniques such as probability random variables distribution functions and density functions. Probability models and random processes are also discussed. Noise representation sources noise factor noise temperature filtering of noise noise bandwidth and performance of AM/FM in presence of noise is discussed in fourth chapter.Analog pulse modulation is presented in fifth chapter. Sampling PAM PAM/TDM are discussed in this chapter. Sixth chapter deals with digital pulse modulation methods such as PCM DM ADM and DPCM.Seventh chapter presents digital multiplexers line coding synchronization scramblers ISI eye patterns and equalization techniques. Digital modulation is presented in eighth chapter. Phase shift keying frequency shift keying QPSK QAM and MSK are presented. Last chapter deals with error performance of these techniques using matched filter.
