The Signal-to-Interference Ratio (SIR) needs to be computed for a transmitter (Tx) located at the centre of a circle, with multiple interferers randomly distributed within the circle.
In the provided code, a loop is used to iterate over each interferer, but the variable ‘SIR_V2V_S’ is overwritten in each iteration instead of storing the result for each interferer.
To fix this, the SIR value for each interferer needs to be appended to the ‘SIR_V2V_S’ array. So, the following line of code
SIR_V2V_S= (P_V.*(r_v.^(-Eta_V)).*Ch_Fading)./((sum((P_V.*hx.*(m.^(-Eta_V)))))+N0);
Should be replaced by:
SIR_V2V_S (end+1) = (P_V.*(r_v.^(-Eta_V)).*Ch_Fading)./((sum((P_V.*hx.*(m.^(-Eta_V)))))+N0);
