“…It is common to use diodes, to perform nonlinear mixing, and a low pass filter to extract the desired baseband parts in outputs of the six-port correlator, as depicted in Figure 1. All formulas which are published for analysing the six-port receiver's performance have modelled diode behaviour as an squared law model (Ghannouchi and Mohammadi, 2009; Askari and Kamarei, 2017; Djoumessi et al , 2009; Bao et al , 2012; Djoumessi and Wu, 2010; Huyart and Khy, 2012; Koelpin et al , 2011; Osth et al , 2010; Tatu et al , 2005; Winter et al , 2007; Zhang et al , 2017; Chagtmi et al , 2017; Song et al , 2018; Neveux et al , 2004; Moscoso-Martir et al , 2011; Mohajer et al , 2007). In this paper, an analytical approach for diode power detector is presented and its influence on six-port receiver performance is studied.…”

Purpose The purpose of this paper is to study the effect of diode power detector modelling on six-port communication receiver performance. Design/methodology/approach Based on proposed and conventional squared diode model, six-port receiver’s demodulation and its error vector magnitude (EVM) performance due to hardware impairments are studied. Through considering both the models, the accuracy of proposed power detector model is compared to the squared model, and then both results are validated with envelope simulation (ENV) in advanced design system (ADS). Findings Comparing the numerical results with envelope simulation results proved that the proposed model is much more accurate than the conventional squared model for a wide range of input power levels. Originality/value Studying the receiver’s performance numerically, by considering the new proposed analytical approach for diode power detectors which is more accurate than the conventional squared model.
