Abstract

It is important to consider transceiver hardware impairments (i.e., imperfect electronic circuits) while designing practical communication systems. Most common transceiver imperfections are oscillator phase noise, I/Q imbalance, amplifier non-linearities, self-interference in a full duplex mode, etc. In this paper, the performance of a dual-hop decode-and-forward underlay cognitive radio network with transceiver hardware impairments and interference power constraints is studied. Closed-form expressions for the exact outage probability (OP) over independent and non-identically distributed Nakagami-m fading channels are presented. More, asymptotic analysis of the OP at high signal-to-noise-distortion ratio values is analyzed. A relation between the hardware impairment level and the transmission rate is investigated using numerical simulations. Hardware impairment level is evaluated for various fading severity parameters of the channel when OP and source power are given. Monte Carlo simulations results corroborate the analytical ones.
