In this work we present solutions which aim at enhancement of the localization precision of the road side unit (RSU) devices which will participate in vehicle-to-infrastructure (V2I) communication in future autonomous driving and intelligent transportation systems (ITS). Currently used localization techniques suffer from limited accuracy which is due to various factors, including noise, delays caused by environmental conditions (e.g. temperature variation) and differences in elevation between devices communicating with each other in the road environment. In case of application of the ITS, these factors can be the source of significant discrepancies between real positions of the RSUs and their estimated values provided by the V2I system. The proposed techniques, based on various approximation techniques, as well as linear and nonlinear filters, allow to improve the localization accuracy, reducing the positioning errors by more than 90 %.

Today there are many wireless communication systems that meet the needs of users, however those systems remains a revolutions regarding the quality and security of service level. In this article, we discuss the comparison of the performance of various wireless communication systems such as WIFI, WIMAX, UMTS, HSDPA, GPRS, GSM, 3G and LTE using a multiple correspondence analysis (MCA) to classify and identify each system by their strong and weak mechanisms in terms of performance based on frequency band, rate, range, access technology, mobility, latency, modulation type and transmission type, in the aim to intended the characteristics that can increase the relevance and quality of the wireless communication system.

“…The available spectrum (3.1-10.6 GHz) (Avila and Thenmozhi, 2014) is divided into 14 sub-bands (Qiyue et al, 2007), each one occupying 528 MHz (Kabil et al, 2011;Avila and Thenmozhi, 2014). The structure of the MB-OFDM solution is very similar to that of a conventional wireless OFDM physical layer, the main difference is the use of Time-Frequency Codes (TFC) (Kabil et al, 2013).…”

“…At the transmitter, the bits from information sources are first encoded by the convolution encoder. To exploit timefrequency diversity and combat multi-path fading, the coded bits are further interleaved according to some preferred time-frequency patterns and the resulting bit sequence is mapped into constellation symbols and then converted into a block of N symbols by the serial-toparallel converter (Qiyue et al, 2007;Kabil et al, 2011).…”

The MB-OFDM has been proposed as a good candidate to ensure Vehicle to Infrastructure communication (V&I). Fast moving vehicles present challenges for the proposed system especially for high mobility (250 km h −1 ). The main objective in this study is to study and investigate the impact of Doppler shift on the quality of transmitted/received signal in terms of Bit Error Rate (BER) and the transmission range. A new solution based on the association of Maximum Likelihood (ML) and Extended Kalman Filter (EKF) algorithmis proposed and computer simulations are performed to confirm the reduction of Doppler impact on the signal quality. Also it is shown that for high value of speed, the new solution can effectively improve the transmission range of the MB-OFDM system.
