PCM记忆重发编码器的设计

针对无线遥测处于黑障区时数据无法实时发送与接收等问题,主要解决在遥测环境复杂,各种干扰因素存在时造成的遥测信息短时中断,产生数据丢帧的问题。运用记忆重发技术,在黑障区实现数据的负延迟存储;经一定时间延迟后将存储器中数据变换为遥测可以接受的码流形式送入采编器进行重新采编,实现数据延迟发送。本文论述了构成新型、灵活的PCM编码器的实现方法,以达到遥测数据的完整性和可靠性。

Design of the PCM memory retransmission encoder

For wireless telemetry blackout zone is not real-time data transmission and reception issues, the article mainly to solve the complex environment in telemetry, there are a variety of disturbances caused by short-term interruption of telemetry information, generate data frame dropping problem. Use of memory retransmission techniques, data in the blackout zone of negative delay memory; after a certain time delay after the data memory can transform telemetry stream acceptable form of editorial control into the re-editing, data delayed sending. This paper discusses the composition of new, flexible PCM encoder implementation, in order to achieve telemetry data integrity and reliability.
