Simulation of 16-QAM Modulation in Rayleigh Channel

This is a simulation of 16-QAM modulation in a Rayleigh channel.

16-QAM modulation in Rayleigh channels represents a fundamental digital communication technique that transmits digital data through quadrature amplitude modulation. This modulation scheme divides signals into 16 distinct phase and amplitude combinations to transmit higher bit rates. The Rayleigh channel models typical wireless transmission environments with multipath propagation and fading effects, making the simulation of 16-QAM modulation performance and robustness under such channel conditions particularly important for system design and analysis.

In code implementation, this typically involves generating 16-QAM symbols using constellation mapping, applying Rayleigh fading through complex Gaussian random variables, and evaluating system performance using metrics like Bit Error Rate (BER) through Monte Carlo simulations. Key MATLAB functions would include qammod for modulation, rayleighchan for channel modeling, and awgn for additive white Gaussian noise implementation.
