Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] In the description of the present invention, unless otherwise stated, the meaning of "plurality" is two or more; the terms "upper", "lower", "left", "right", "inner", "outer" , "front end", "rear end", "head", "tail", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than Nothing indicating or implying that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation should therefore not be construed as limiting the invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importa...

Abstract

The invention discloses a Chinese and English hybrid coding method in narrowband communication. The method comprises the following steps: judging character information to be sent of narrowband communication equipment one by one; the characters judged to be Chinese, the characters judged to be English numeric symbols and the characters judged to be full-angle symbols are combined into a byte array according to the character information sequence, and coding is completed. According to the Chinese and English mixed coding mode, the English numeric symbols only occupy one byte, all numbers and symbols are coded through ASCII, and the coding efficiency is improved. Under the condition that communication text content is kept unchanged, communication bytes are effectively reduced, the same communication word can bear more text content in an energy-saving mode, information transmission is facilitated, and the whole coding method and the corresponding decoding method are simple in principle, easy to achieve and convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of coding and decoding, in particular to a Chinese-English mixed coding method in narrowband communication. Background technique [0002] Now network communication technology is dominated by broadband communication technology, basically there is no need to consider the issue of command length when sending commands. However, in some dedicated communication networks, they are all narrowband, such as digital radio, Beidou short message, PSTN and other communication methods. In narrowband communication, when sending Chinese text information using Unicode, UTF, GBK and other encodings to transmit, at least 2 bytes are required to represent a character, and each communication transmits tens or hundreds of bytes, or even a few dozen Byte, when it is necessary to send text information (such as TTS text information) during the communication process, if all are transmitted according to the Chinese code (Unicode), for...
