| titleOfInvention | Car based on OFDMA access technology networking uplink synchronous system and method |
| abstract | The invention discloses car based on OFDMA access technology networking uplink synchronous system and method, this system includes for being divided into M sub-channels by Common transport channel of being networked by car, be easy to multiple On-Board Unit OBU and send the emitter of transmission opportunity request frame in respective sub-channel, and the OFDMA signal of the user's input being successfully connected in car is networked sequentially passes through shift frequency filtering extraction and FFT processes the input data separating of each user out, realize multiple On-Board Unit OBU accesses the receiver of unit R SU on road simultaneously；Described emitter and receiver wireless connection, M=1,2,4.Car based on OFDMA access technology of the present invention networking uplink synchronous system and method, the defect such as can overcome in prior art that system throughput is low in the presence of a large amount of OBU, system delay is high and reliability is low, to realize the advantage that system throughput is high, system delay is low and reliability is high under the above conditions. |
