A Short Course on DSRC/LTE

PDSCH Matlab/MEX Simulation Program Included

[Course Introduction] The short course is co-sponsored by Odyssia Global Communications and Shanghai Yong Chang Information Technology Company. In this short course, we will teach the state-of-the art of vehicular wireless networks built upon long term evolution (LTE) or dedicated short range communications (DSRC) in its fundamentals, algorithms, schemes, systems design, simulations and implementations. The course contents cover the principles of orthogonal frequency-division multiplexing (OFDM) and multiple input multiple output (MIMO) technology, vehicular channel models, baseband algorithms, field programmable gate array (FPGA) based implementation and prototyping, vehicular network simulator, and experiments. All contents are abstracted from ongoing research activities and projects that are being conducted at the Center for Vehicular Communications and Networks at University of Michigan, Dearborn, funded by two NSF Grants, a CISCO University Research Grant and a project of TD-LTE prototyping for high-speed trains in China.

[Features] The LTE link level simulator is a comprehensive simulation software used for algorithm development, performance evaluation and system validation associated with LTE systems. The simulator have Matlab and C versions. The C version simulator consists of optimized algorithms which can be easily transferred to DSP platform. All the functional blocks provide dynamic memory allocation for data blocks and easy settings of parameters offering advanced user flexibility to customized simulation. When compared to other LTE simulation tools such as Steepest Ascent LTE toolbox and IsWireless LTE PHY Lab, our software not only provides a friendly GUI with various settings, user defined input and output data, and open architecture to integrate user defined function blocks, but also integrates our proprietary high-speed channel models for vehicle applications and high-speed trains applications. The  The key features of the LTE link level simulator are summarized as below: 1) fast simulation speed, 2) Affordable license fee, 3) 3GPP Release 9/10 LTE physical layer, PDSCH & PUSCH, 4) FDD/TDD mode, 5) LTE M2M, 6) User defined input and output data, 7) Interface to integrate user defined function blocks, and 8) Support all 15 Winnter II LTE channel models as well as vehicle channel model and high-speed train channel mode.

The First DSRC/WAVE OUB/RSU

[Key Technologies] We offer off-the-shelf real-time full functional wireless wireless access for vehicular environments (WAVE) onboard unit (OBU) and roadside unit (RSU) based on the IEEE 802.11p standard. WAVE requires intensive R&D and manufacture activities including function definition, algorithm development, system design, prototype assessment and massive production. The enormous market need of WAVE production could sustain one or several tier-one automobile large suppliers and many surrounding companies. Thousands of workshops are in need to install WAVE devices to existing billions of vehicles. Moreover, the WAVE service could foster one or several service operators with comparable sizes as big as cellular carriers. In summary, WAVE generates a fresh information technology industry on vehicle basis and brings up an opportunity to enhance the quality of life and intensify automobile’s high-tech ingredients and competitiveness. The magnitude and degree of the impacts on Automobile industry in the worldwide are substantial, multi-layered and profound.

WAVE systems offer enhanced safety, intelligent traffic management and wireless access for vehicles through the high-speed wireless links between vehicles and between vehicles and the roadside access points (APs) based on the IEEE 802.11p standard, ratified in 2010. By adopting orthogonal frequency multiplexing division (OFDM) modulation scheme, WAVE systems achieve a data rate of 6-27Mbits/s and a WAVE device covers a range of 1000 feet. The Federal Communication Commission (FCC) has assigned the 5.850-5.925GHz band for the operation of WAVE systems. The key technologies include, 1) Novel multiple-stage Doppler frequency detector and proactive channel estimator under diverse doubly selective vehicular channels, 2) Complete IEEE 802.11p PHY and MAC protocol stacks, and 3) Software radio capability with multiple work modes (Option)
