Digital communication systems employ various modulation schemes, with 16QAM being a widely-used quadrature amplitude modulation technique that combines both amplitude and phase keying. This code simulation demonstrates 16QAM constellation diagrams, symbol error rate (SER), and bit error rate (BER), illustrating their interrelationships through MATLAB implementation. The simulation provides practical insights into QAM performance analysis, covering modulation techniques like 32QAM, 64QAM, and 56QAM, making it valuable for understanding digital communication system optimization.

MATLAB implementation for generating 16QAM baseband signals with real-number interpolation. The system operates at 1 MSymbol/s symbol rate using root-raised cosine filtering with roll-off factor=0.5. A pseudo-random sequence {…1, 0, 1, 1,…} undergoes constellation mapping, 4x shaping filter, FIR half-band filtering, and real-number interpolation filtering, ultimately producing 4.315x time/frequency domain responses. The implementation includes comprehensive time-domain and frequency-domain analysis at each filtering stage.
