DEDICATED SHORT-RANGE COMMUNICATION MIMO-SYSTEM WITH CARRYING CAPACITY CLOSE TO SHANNON'S LIMIT FOR VEHICLE-TO-VEHICLE DATA TRANSMISSION ON HIGHWAY
Краткое описание
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 totally off-line operation of the vehicle equipped with this system at the complete absence of base stations as a rule controlling mobile communication systems. The method suggested gives a possibility to practically realize both a Space-Code Division Multiple Access (S-CDMA) mode and data transmission principles based upon 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 a temporal channel for each vehicle and perform data reception on the search less basis. Application of S-CDMA mode in combination with chaotic waveform encoding for implementing CDMA-standard are distinguishing features of the suggested EU DSRC-VVDT MIMO-system. The key method idea is to associate a unique code for every vehicle in the EU DSRC-VVDT MIMO-system not with a vehicle itself, but with its current position in a highway. This approach enables usage of identical standard Tx/Rx equipment installed at all vehicles. Self-organizing MIMO-system allows practical realization (for a maximally possible number of vehicles) of the channel carrying capacity close to Shannon's limit.
