This paper reflects the LTE physical layer performance by BLER curves of different number of antennas and adopt transmitting diversity or spatial multiplexing under the same number of antennas. In addition, the next simulation adopts HARQ based on the above, maintaining new BLER curves. The result of this simulator serves to evaluate the OFDM-MIMO LTE Link Level performance in different environments...
Today, the collaboration between the mining management and the use of computers are strictly limited to above the ground. When accidents happen, rescuers cannot receive the accurate information about the precise location of the trapped workers. A new mine workers' precise location system project based on the Radio Frequency Identification (RFID) technology is proposed. This project uses RFID technology...
This paper first analyses the proportional-fair scheduler for packet business. Then the improved proportional-fair scheduler for HSDPA is put forward, with the business priority, data volume cache, the ratio of real-time rate and average rate using as the basis to amend the packet scheduling rate. The improved scheduler can handle the packet scheduling for multi-users within the same period, so as...
This paper describes making use of the business volume of packet service and QoS attribute, adopting dynamic method to adjust the wireless resources to improve the utilization of wireless resources.
This paper provides a time synchronization method which is suitable for TD-SCDMA home base stations, based on existing solutions to solve the problem of home base station's time synchronization problem. It presents two operating modes to TD-SCDMA home base station, namely UE operating mode and home base station operating mode. Before entering home base station operating mode, it achieves the TD-SCDMA...
Based on the wireless communication platform provided by 3G mobile communication systems, this paper studies wireless location application solutions and provides a new application system solution. Also, this paper expounds the system principle, framework design and specific technical layout of the new application system solution.
