Future cellular networks need to reduce their carbon footprint in view of rapidly increasing data traffic from emerging applications including Augmented Reality (AR)/ Virtual Reality (VR), autonomous vehicles and Internet of Things (IoT).

In this paper, we look into the performance of decode-and-forward (DF) relaying system in the presence of both channel estimation error (CEE) and radio frequency impairments (RFI). We have sub-divided the analysis into different cases based on the presence of RFI at the relay, source and destination.

This paper presents the performance analysis of decode-and-forward (DF) relaying system in presence of both channel estimation error (CEE) and radio frequency impairments (RFI). First, the end-to-end signal-to-noise-plus-distortion-and-error ratio (SNDER) expression is derived, followed by an exact closed-form outage probability (OP) expression for Nakagami-m fading channel.
