The effects of different noise types and mobility on error rate of digital modulation schemes over millimeter-wave Weibull fading channels

Abstract

Millimeter (mm-wave) communication is a prominent candidate to support the evolution towards fifth generation (5G) wireless systems. As such, in this paper, we study the impact of different noise type and mobility on the performance of coherent binary digital modulation schemes in mm-wave Weibull fading channels. To this end, exact and new closed-form expressions are derived for the bit error rate of coherent digital modulation schemes in millimeter wave Weibull fading channels in the presence of additive non-Gaussian noise. In addition, new and exact closed-form expressions are obtained for the symbol error rate of square M-ary quadrature amplitude modulation scheme (M-AQM). The derived expressions take into consideration the mobility of the wireless receives. Besides, they are valid for integer and non-integer values of the fading and noise shaping parameters. Analytical results are supported by Monte-Carlo simulations to validate the accuracy of the obtained results.
