| 摘 要： | 本文提出了两种无线TCP改进机制,即:基于重传率调整TCP段尺寸的机制和基于吞吐量估计设置往返时间(RTT)门限检测网络拥塞的机制.大量的仿真结果验证了两种新机制的可行性和有效性.这两种机制可在未来有线/无线混合因特网中有效地改善TCP连接的性能,提供高效而可靠的端到端无线/有线混合因特网服务.

| Abstract: | The realization mode of solving ambiguity for multiple frequency ranging usually has two kinds:quadric difference frequency and uneven dual frequency.The former has the advantages such as simple principle and easy design of receiver and transmitter.This paper deduces the principle of ranging based on quadric difference frequency in details and analyzes the need for SNR when solving ambiguity correctly.Finally simulation results verify the validity of the method.It provides the theory basis for design of multiple frequency CW ranging radar. |

| Keywords: | dual frequency ranging multiple frequency ranging quadric difference frequency SNR |
