Embodiment Construction

[0065] Aiming at the problem existing in the prior art that the wireless network system where the train of the high-speed railway is located cannot ensure the maximum throughput rate, thereby wasting network resources, the embodiment of the present invention provides a signal demodulation method, which is applied to a fixed AP. The fixed AP can be, but not limited to, an AP set at a fixed location near the high-speed railway in the wireless network of the high-speed railway. The process of the method is as follows: figure 1 As shown, the execution steps are as follows:

[0066] S11: Broadcast the parameter value of the leading parameter, so that the mobile AP that receives the parameter value of the leading parameter and needs to obtain data calculates the parameter value of the setting parameter according to the parameter value of the leading parameter, and then returns the parameter value carrying the setting parameter The data acquisition request message for .

Abstract

The invention discloses a signal demodulation method and device. The method includes: broadcasting the parameter value of the leading parameter, so that after the mobile AP calculates the parameter value of the setting parameter according to the parameter value of the leading parameter, it returns the The data acquisition request message of the parameter value; according to the parameter value of the set parameter sent by the mobile AP and the average throughput rate of each signal demodulation scheme in the pre-established signal demodulation scheme set, obtain the selected signal from the signal demodulation scheme set Signal demodulation scheme; modulate the obtained data according to the modulation order included in the selected signal demodulation scheme and the demodulation pilot placement sub-scheme to obtain modulated data; obtain the response with the data carrying the modulated data and the selected signal demodulation scheme The message is sent to the mobile AP, so that the mobile AP demodulates the modulated data according to the selected signal demodulation scheme, and obtains the obtained data. This solution can ensure the maximum throughput rate of the wireless network system where the train of the high-speed railway is located, thereby saving network resources.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a signal demodulation method and device. Background technique [0002] In recent years, the rapid development of China's high-speed railway (High Speed ​​Railway, HSR) has promoted the rise and development of other related industries, such as communications, machinery manufacturing, and electric power, which in turn has produced huge economic benefits. Nowadays, high-speed rail is already an important way of travel. In addition, the 5G era is getting closer and closer. Mobile communication has become an indispensable part of high-speed rail services. At present, the wireless network used by passengers on high-speed rail trains is still public. When the train is running at high speed, the Internet access rate is extremely low and the user experience is poor. Therefore, it is very important to develop a wireless network specially used in high-speed railways. [0003] Orthogo...
