PSpice for Digital Communications Engineering

The book delves into simulating digital communication systems using Cadence Orcad PSpice, focusing on modulation techniques and signal analysis. It covers foundational concepts like Fourier series and transforms, explores various baseband signals, and examines their limitations in public networks. Key topics include pulse code modulation, time-division multiplexing, and the effects of noise. Advanced modulation techniques such as QPSK and QAM are analyzed, alongside bandwidth efficiency and channel capacity. The final section addresses direct spread spectrum for enhanced signal security.
