Co-Channel Interference and Background Noise in $\kappa$ - $\mu$ Fading Channels

In this letter, we derive novel analytical and closed form expressions for the outage probability, when the signal-of-interest (SoI) and the interferer experience
$\kappa $
–
$\mu $
fading in the presence of Gaussian noise. Most importantly, these expressions hold true for independent and non-identically distributed
$\kappa $
–
$\mu $
variates,
without
parameter constraints. We also find the asymptotic behaviour when the average signal to noise ratio of the SoI is significantly larger than that of the interferer. It is worth highlighting that our new solutions are very general owing to the flexibility of the
$\kappa $
–
$\mu $
fading model.
