A signal processing method, system, access point and mobile station

Abstract

The embodiment of the invention provides a signal processing method and system, an access point and a mobile station. The method comprises the following steps: acquiring measurement information corresponding to each sending branch in multiple sending branches deployed in wide area; selecting a target sending branch from multiple sending branches based on the measurement information, wherein the amount of the target sending branch is in the first interval range; respectively sending a configuration message frame to the mobile station by adopting the target sending branch; receiving a configuration response message frame returned by the mobile station and corresponding to the configuration message frame; and sending a data frame to the mobile station by adopting the target sending branch based on the configuration response message frame. Through the signal processing method provided by the embodiment of the invention, a deep attenuation problem of a short-wave channel is solved by transmitting a space attenuation unrelated signal by using multiple sending branches deployed in wide area, the channel adaption capacity of the short-wave system is improved, and then the passability is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a signal processing method, a signal processing system, an access point and a mobile station. Background technique [0002] As a means of communication that does not depend on easily destroyed fixed infrastructure, short-wave communication has the advantages of long communication distance, flexible maneuvering, and convenient networking. "Integrated collaboration provides important basic capability support. However, because short-wave communication relies on unstable atmospheric ionospheric reflection, short-wave channels have the characteristics of time-varying dispersion, fading, and serious interference. At the same time, with the deteriorating electromagnetic environment faced by the short-wave frequency band and the communication needs of long-distance and high-dynamic battlefield environments, it is imminent to improve the throughput and communication qualit...

Problems solved by technology

However, since the long-distance short-wave communication uses sky-wave communication based on the ionospheric reflection mechanism, when multiple transmitting branches are arranged in the same access point, since the transmitting branches are located in the same area and the distances are close, the accuracy of the multiple transmitting branches cannot be guaranteed. Fading independence, there will still be deep fading at the same time, so it is difficult to solve the accessibility problem of the shortwave system
