高速电缆遥测──超过500kb／s数传速率的电缆遥测系统

Cable Telemetry System with Data Transmission Rate over 500 kb/s

提出了超过５００ｋｂ／ｓ数传速率的高速电缆遥测方案，讨论了相关编码、正交调幅、匹配滤波、基带均衡、最大似然比序列估计、电缆多路复用等技术在电缆遥测中的应用，分析了国际先进遥测系统可能采取的方案，指出电缆遥测系统的研制时机已经成熟。

In this article, the technical scheme of high-rate cable telemetry system withtransmission rate over 500 kb/s is put forward. The applications of correlative coding, quadrature amplitude modulation, matched filtering, baseband equalization,maximum likelihood sequence estimation, and cable multiplexing to cable telemetryare discussed. Some possible approaches of several modern telemetry systems areanalyzed. It is also pointed out that the time has come to catch up with the world's advanced level in cable telemetry technology.
