Abstract

The invention provides a TCP improvement method for long delay and large bandwidth application demands. The method comprises the following steps: obtaining a relatively accurate receiver signal measurement result through delay correction, establishing coded modulation scheme protection ranges corresponding to various delay levels, and selecting a coded modulation scheme within the protection ranges to communicate with a receiver by a sender. By adoption of the TCP improvement method for long delay and large bandwidth application demands provided by the invention, fast and accurate changes of matched channel states are ensured, the transmission error probability is reduced, and a WIFI system can be guaranteed to work in the optimal state.

Description

technical field [0001] The invention relates to a wireless network, in particular to an improved method for long-time-delay and large-bandwidth application requirements. Background technique [0002] WIFI technology has developed rapidly and has become the most popular and universal network access technology in the world. Basically, all user mobile devices, including smartphones, tablets, and laptops, have WIFI access capabilities. But at the same time, the crosstalk problem of the WIFI system has gradually become the most problem affecting the actual deployment, including microwave, Bluetooth, radar and other crosstalk and crosstalk between systems. In order to solve the crosstalk problem of the WIFI system, the solution adopted in the prior art is mainly to expand new frequency band resources and reduce the probability of duplication of working channels. However, as more users choose WIFI to access the Internet, and the bandwidth demand of 802.11ac to reach the peak value...
