What is the benefit of using SINR as opposed to SNR to reference signal quality...

SINR vs. SNR:

SNR (Signal-to-Noise Ratio): Measures the power of the desired signal relative to background noise.

SINR (Signal-to-Interference-plus-Noise Ratio): Considers both background noise and interference from other signals operating on the same frequency.

Practical Importance: SINR is a more realistic indicator of real-world signal quality in wireless environments where interference is a significant factor.
