MIMO-SYSTEM WITH CARRYING CAPACITY CLOSE TO SHANNON'S LIMIT FOR VEHICLE-TO-VEHICLE DATA TRANSMISSION ON HIGHWAY

Abstract

A new approach to design of the self-organizing MIMO-system using European Union Dedicated Short-Range Communication (EU DSRC) standard for Vehicle-to-Vehicle Data Transmission (VVDT) within a highway area of 1 km in radius is proposed. The design method of self-organizing EU DSRC-VVDT MIMO-system provides the completely off-line operation of vehicle appointed by this system at the complete absence of base stations as a rule controlling mobile communication systems. The method suggested gives the possibility in practice to realize a Space-Code Division Multiple Access (S-CDMA) and the principles of data transmitting with the usage of broadband chaotic waveform sequences and unique binary pseudorandom sequences. In addition, these code signals give a potential capability for design of a self-organizing EU DSRC-VVDT MIMO-system without allocating a frequency or temporal channel for each vehicle and perform data reception on the searchless basis. Combination of spatially code channels separation (S-CDMA) and chaotic waveform coding for implementing CDMA-standard are distinguishing features of the suggested EU DSRC-VVDT MIMO-system. The key method idea is to associate the unique code for every car in the EU DSRC-VVDT MIMO-system not with a car, but with its current position on highway. A new method for the S-CDMA-code prescribing to each car within the working range of EU DSRC-VVDT MIMO-system enables usage of identical standard Tx/Rx equipment for all vehicles. The self-organizing MIMO-system allows to implement in practice, for the maximally possible amount of transport vehicles, the carrying capacity of channel close to Shannon's limit.
