Improved analytical approach for studying the effect of diode power detector modelling on six-port communication receiver performance

Abstract

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.
