A Review on Two-Way Relaying Transceiver Hardware Impairments

Hardware impairments in physical transceivers are acknowledged to have a lethal consequence on communication systems; Even though very scarce contributions have examined their influence on relaying. This paper gives a review one numerating effect in a two way amplify-and-forward (AF) configuration of transceiver impairments. More precisely the real signal to noise and distortion ratios at both transmitter nodes are attained. These are used to calculate asymptotic and precise closed form expressions for the outage probabilities, as well as submissive expressions for Symbol Error Rate (SER). It is clearly revealed that non-zero lower limits on the SER and Outage Probability (OP) occur in the high-power regime this stance in divergence to the distinct case of ideal hardware, where the SER and OP tends asymptotically to zero.
