“…Ahmed et. al [39] have evaluated the performance of an F-OFDM system with turbo and convolutional coding for a UWA channel that was statistically characterized using Tdistribution. F-OFDM is a promising technique for future 5G networks due to its ability to reduce OOB emissions, decreasing PAPR of the system and implementation simplicity.…”

“…The beacon message includes location, velocity, direction, acceleration [2], [3]. To secure communication between the vehicles, the vehicles must be equipped with a device called onboard unit (OBU) [4], [5]. These messages are sent wirelessly, so the driver can be easily tracked by the attacker.…”

With increase in the population, the number of registered vehicles has dramatically increased over all the world, and this leads to a high rate of traffic accidents on the roads. Therefore, in order to prevent such accidents, an Intelligent Transportation Systems (ITSs) is needed to be installed to notify drivers of obstacles in advance. Recently, the Internet of things (IoT) evolves the vehicular communications and covers this technology under the Internet of vehicles (IoV) application. IoV is a new field for the automotive industry and a significant part of the smart cities. However, protecting the privacy of vehicle's location is the most challenging subject in the vehicular communication, as because it threatens the personal life of drivers. This paper provides cooperation and radio silence strategy in mix zone (CRSMZ) to protect location privacy of vehicle in IoV. The strategy implements either cooperation or radio silence depending on the speed of the vehicle while it is in mix _zone. The simulation results show that CRSMZ is an efficient strategy to protect location information of vehicle drivers. CRSMZ outperforms the existing strategies in terms of mean of the number tracker confusion, continuous tracking period and max of the entropy.

“…Due to the distinguishing features of OFDM frameworks, many wireless systems adopted the OFDM as a reliable data trans-mission technique in modern communication environments. The OFDM system is differentiated by some distinctive features, for example, high system capacity, the efficiency of bandwidth utilization, immunity to inter-symbol-interference, and robustness against multipath fading [1] [2]. Consequently, the OFDM system adopted by numerous communication systems such as broadcast radio access network (DRAN), digital video broadcasting (DVB), and digital television broadcasting (DTVB) [3] [4].…”

Partial transmit sequence (PTS) is considered an efficient algorithm to overcome the problem of high peak to average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. PTS technique is depending on the partitioning of the input data sequence into the several subblocks, and weighting these subblocks with a set of the phase rotation factors. There are three common types of partitioning schemes: interleaving scheme (IL-PTS), adjacent scheme (Ad-PTS), and pseudo-random scheme (PR-PTS). The three ordinary partitioning schemes have various performances in terms of the PAPR reduction and the computational complexity. In this paper, the three ordinary partition schemes are analyzed and discussed depending on the PAPR mitigation performance and the computational complexity. The simulation results indicated that the PR-PTS scheme could achieve the superiority in terms of PAPR reduction compared with other schemes. Furthermore, the numerical calculations recorded that the computational complexity of the ordinary partitioning schemes increases exponentially with increasing the number of the subblocks.
