LTE‐DSRC hybrid vehicular communication system using DFT‐spread OFDM in uplink

Abstract

Summary Technologies are advancing at a rapid rate in the current era. People are advancing with the advancement of technologies, be it in education industry, health industry, and providing luxury. With the advent of autonomous luxury‐in‐motion car that provides in‐car‐entertainment (ICE), vehicular communication is the prerequisite towards achieving this goal. Dedicated short range communication (DSRC) is a matured vehicular communication standard, and Long‐Term Evolution (LTE) is the most competing technologies in the cellular communication. In this paper, we focus on the uplink performance of the LTE‐DSRC hybrid infrastructure. The basic transmission scheme for uplink direction is based on single carrier transmission in the form of discrete Fourier transform (DFT)‐spread Orthogonal Frequency Division Multiplexing (OFDM) with a minimum mean square error (MMSE) receiver at the LTE Evolved Node B (eNodeB) and a DSRC OFDM transmitter. A comprehensive bit error rate (BER) performance simulative study has been made on a color image transmission in uplink hybrid LTE‐DSRC system, and the results obtained are encouraging that the proposed convergence is possible, as it provides a substantial decrease in the BER with a gradual increase in the signal ‐to‐ noise ratio Signal to Noise Ratio (SNR).

“…In terms of shorter distances and conveyance of safety messages this spectrum is sufficient for stand‐alone systems. However, with the technological advancements, hybrid systems crept up where technologies are converged for efficient communication 74,226–239 . Therefore, more bandwidth and resource allocation methods are required for efficient luxurious services such as sending/retrieving of multimedia services and online streaming.…”

With the concept of CB, sufficient bandwidth can be allocated to services requiring higher bandwidth or dynamic bandwidth resource allocation can be implemented with the basic idea of CB.…”
