EVM Performance Metrics for QPSK, 16QAM, and 64QAM Modulation Schemes

Our team has developed computational code to evaluate EVM (Error Vector Magnitude) metrics for QPSK, 16QAM, and 64QAM modulation schemes. The implementation employs constellation diagram analysis and error vector calculation algorithms to derive critical signal quality indicators. Our code architecture includes modules for handling channel impairments such as additive white Gaussian noise (AWGN), multipath fading, and interference effects through configurable SNR settings and channel models. The system utilizes signal processing techniques including synchronization, equalization, and symbol decision mechanisms to ensure accurate EVM measurements across different modulation orders. Users can efficiently compute and compare EVM performance under various modulation schemes through parameterized function calls, providing valuable references for wireless communication system design and optimization. The modular code structure allows for extensibility to additional modulation types and channel conditions.
