OFDM Simulation with 16QAM Modulation: AWGN and Multipath Channel Modeling

This simulation implements OFDM with 16QAM modulation under both AWGN and multipath channel conditions. The implementation provides a solid foundation for initial algorithm development, supporting various testing and optimization scenarios through modular code structure. During the simulation process, you can test different parameters and configurations to evaluate system performance. The code allows experimentation with various signal-to-noise ratio (SNR) values, different modulation schemes (easily interchangeable through configuration variables), and alternative channel models for comparative analysis. Key functions include channel model initialization, modulation/demodulation blocks, and BER calculation modules. Furthermore, you can optimize and improve algorithms to enhance system robustness and performance. The simulation framework supports testing different encoding and decoding schemes (such as convolutional or LDPC codes), and allows implementation of various channel equalization algorithms (like Zero-Forcing or MMSE equalizers) to mitigate channel effects. The equalization module typically includes channel estimation and compensation routines. In summary, this OFDM simulation serves as a valuable tool for gaining deep insights into system behavior and performance characteristics. It provides guidance and support for algorithm development through comprehensive testing capabilities and modular design that allows easy extension and modification of individual components. The simulation includes performance metrics calculation and visualization functions for detailed analysis.
