Performance of Decode-and-Forward Multihop Networks over i.n.i.d. Nakagami-m Fading Channels

Abstract

In this work, performance analysis of multi-hop networks over independent but non-identically distributed (i.n.i.d.) Nakagami-m fading channels for half-duplex (HD) and decodeand-forward (DF) transmission protocols is revised. The closed form expressions of outage probability (OP), moment generating function (MGF), symbol error rate (SER), and ergodic capacity (achievable rate) are derived. The obtained expressions are simpler than the existing ones. The validity of OP, SER, and ergodic capacity expressions is shown via Monte Carlo simulation technique.
