Source Code from the Book "Modern Communication Systems Using MATLAB"

In modern communication systems, MATLAB serves as a widely adopted tool for modeling and simulating communication systems. The book "Modern Communication Systems Using MATLAB" provides comprehensive source code examples that demonstrate practical implementation of communication algorithms, including digital modulation schemes, error-correcting codes, and channel modeling techniques. These code examples feature key MATLAB functions such as comm.QPSKModulator for quadrature phase-shift keying, comm.AWGNChannel for additive white Gaussian noise simulation, and comm.RSEncoder for Reed-Solomon error correction implementation. The accompanying theoretical sections deepen understanding of communication system fundamentals, enabling more effective application of MATLAB for system analysis and performance evaluation. The resource offers valuable practical implementations of communication system components, including filter design using fir1 function, spectral analysis with fft algorithms, and bit error rate calculation through monte carlo simulations. This combination of theoretical foundation and hands-on code examples provides an essential resource for mastering modern communication system design and simulation methodologies.
