SINR (Signal to Interference and Noise Ratio) measures the strength of a desired signal relative to interference and noise. It is the ratio of signal power to the sum of interference power and background noise power.
SINR = signal power / (noise + interference power)
SINR_optimization adjusts power levels to maximize signal quality for two signals in a wireless network. It considers transmitter-receiver distances (d1, d2, d3, d4) and signal strength, running various scenarios to calculate the SINR sum.
The goal is to find optimal power levels (p1 and p2) that maximize SINR and ensure clear transmission, using minimization techniques and random settings.
