With the growing demand for higher data rates and improved spectral efficiency in modern communication systems, understanding the ability of higher-order modulation schemes such as 16 Phase Shift Keying (16-PSK) to resist interference or fading conditions is essential, particularly under realistic channel impairments. This paper provides a performance analysis of 16-PSK modulation in a wireless system, under the impact of Adjacent Channel Interference (ACI) and Co-Channel Interference (CCI) across fading channel environments. Additionally, it's evaluating the system performance over both Rayleigh and Rician fading channels using various MIMO (Multiple-Input Multiple-Output) configurations, including 2×2, 2×3, and 2×4 setups. The simulation model was built using MATLAB Simulink to evaluate Bit Error Rate (BER) as a function of Signal-to-Interference Ratio (SIR) and Energy per Bit to Noise Power Spectral Density (Eb/N₀).
