functions will be derived and validated through Monte-Carlo simulations results.
• 2.The close-from expressions of ASC, SOP, SPSC will be derived and enhance
performance with the number of fading parameter & normalize variance parameter.
• 3. The performance of HD technique outperforms of with IM/DD.
