Simulación y análisis de los modelos de propagación para un canal implementado bajo el estándar IEEE 802.11p

Abstract

The evolution of intelligent transport systems (ITS) has given way to the development of new communication technologies that allows to improve the operation and safety of ground transport. To support these applications, improvements to the IEEE 802.11 standard are defined, creating the IEEE 802.11p amendment, which defines both the physical layer (PHY) and the media access control layer (MAC, Media Access Control) in the 5.9 GHz frequency band. This final career project analyzes the propagation models that best fit a communication under this standard. The design and implementation in MATLAB of the physical layer of an IEEE 802.11p transmitter and receiver over AWGN channel is shown, which includes small and large-scale fades. The propagation models that best suits a communication on the IEEE 802.11 are analyzed in terms of PER (Packet Error Rate) vs SNR (Signal to Noise Ratio) and PER vs distance for each propagation model.
