The Beidou short message user terminal demodulates and decodes the outbound signal according to the information rate indication in the received outbound signal, and records all correctly decodable information rates to form a set {R i }.
S13、从可以正确解调和译码的出站信息速率{Ri}中，选择信息速率最高的速率Rmax＝max{Ri}，作为本次通信的出站信息速率指示，并将该信息调制在入站信号中，通过北斗卫星转发至给北斗短报文通信系统的中心站；S13, from the outbound information rates {R i } that can be correctly demodulated and decoded, select the rate with the highest information rate R max =max{R i } as the outbound information rate indication for this communication, and modulate the information into the inbound signal, and forward it to the central station of the Beidou short message communication system via the Beidou satellite;
其中，该入站信号的信息速率通过下文的入站信息速率选择方法获得；The information rate of the inbound signal is obtained by the inbound information rate selection method described below;

The central station of the Beidou short message communication system receives the user's inbound signal, obtains the outbound information rate indication information selected by the user, and modulates and transmits the outbound information according to the information.
本发明的基于北斗短报文用户终端信号强度测量的入站信息速率选择方法，包括下列步骤：The inbound information rate selection method based on Beidou short message user terminal signal strength measurement of the present invention comprises the following steps:
S21、北斗短报文用户终端接收短报文出站信号，得到信号载噪比的估计量CN0r；S21, the Beidou short message user terminal receives the short message outbound signal and obtains an estimate of the signal carrier-to-noise ratio CN0 r ;
S22、选择载噪比CN0r最大的卫星作为入站转发卫星；S22, selecting the satellite with the largest carrier-to-noise ratio CN0 r as the inbound forwarding satellite;
S23、利用出站信号载噪比CN0r，根据北斗短报文中心站与用户终端之间链路预算的相对关系，推算入站链路的载噪比大小，具体方法如下：S23. Using the outbound signal carrier-to-noise ratio CN0 r , according to the relative relationship of the link budget between the Beidou short message center and the user terminal, the carrier-to-noise ratio of the inbound link is calculated. The specific method is as follows:

According to the calculated inbound carrier-to-noise ratio CN0 s and the demodulation thresholds at different inbound information rates, the corresponding information rate is selected for inbound. FIG2 shows the demodulation thresholds of different inbound information rates of the Beidou short message system. It can be seen that
