Embodiment

[0014] A data compression method for Beidou to send and receive Chinese character text messages, specifically including the following steps:

[0015] Step 1, the encoding of the Chinese characters to be sent is re-encoded;

[0016] Domestic Chinese character information is usually encoded with GB2312. This invention only compresses Chinese character information using GB2312 encoding. If the Chinese character information to be compressed is in other encoding formats, the Chinese character information to be compressed can be converted into GB2312 encoding before using the present invention The method performs compression.

[0017] The GB2312 standard contains a total of 6,763 Chinese characters. In GB2312, the collected Chinese characters are "divided", and each area contains 94 Chinese characters / symbols. This representation is also called area code.

[0018] Areas 01-09 are special symbols;

[0019] Areas 16-55 are first-level Chinese characters, sorted by pinyin;

[0020]...

Abstract

The invention discloses a data compression method used during Big Dipper reception and transmission of Chinese character text massages. According to the characteristic of Chinese character GB2312 encoding, re-mapping is carried out on the GB2312 encoding, so as to reduce binary system bits needed by representing each Chinese character, thereby realizing compression on Chinese character texts. When the method is adopted for compressing and decompressing, increase of extra storage consumption is not needed, the use is simple, the performance is stable, the reliability is high, and the data compression method is suitable for data compression when the Big Dipper equipment is used for sending out general Chinese character text massages.

Description

technical field [0001] The invention relates to a method in the field of information and signal processing, in particular to a data compression method for Beidou to send and receive Chinese character text messages. Background technique [0002] With the urgent demand for general aviation applications from the people and the strong support from the state to the general aviation industry, the general aviation market is booming. However, real-time data communication during flight is extremely important for the user and management of general aircraft. Civil aviation aircraft have their own communication base stations, and civil aviation aircraft only fly within the coverage of communication base stations, so civil aviation aircraft do not have communication blind spots. However, general aircraft may fly in blind areas without communication base stations, so other communication means need to be used. The Beidou system independently developed by my country is very suitable for d...
