Device, method and transmission system for encoding and decoding multiple signals

Abstract

The invention discloses a device and method for encoding and decoding multiple paths of signals and a system for transmitting multiple paths of signals. The encoding device includes: a conversion module used for converting a first signal into a bipolar reference signal; a polarity destruction point setting module used for, in a time interval corresponding to a low level of a second signal, after determining a first pulse of the bipolar reference signal which is the closest to the rising edge of the second signal, setting a polarity destruction point at the position of the first pulse; and a polarity destruction loss point setting module used for, in a time interval corresponding a low level of a third signal, after determining a second pulse of the bipolar reference signal which is the closest to the rising edge of the signal, setting a polarity destruction loss point at the position of the second pulse. The transmission system provided by the invention can realize hybrid encoding of multiple signals to perform transmission in a same signal, thereby saving routing resources, and reducing design cost and complexity.

Description

technical field [0001] The present invention relates to the field of computer networks, in particular to a device for encoding and decoding multi-channel signals, a method for encoding multi-channel signals, a method for decoding multi-channel signals, and a method for decoding multi-channel signals system for transmission. Background technique [0002] In a narrowband access system, a clock signal and a frame header signal are required, wherein the frame header signal is used to identify the starting position of the data signal, and the clock signal is used for synchronization. Commonly used clocks are the first clock signal and the second clock signal with a frequency of 16.384MHz and 2.048MHz, and the duty cycle of the two clock signals is 50%; the frame header signal is usually a signal with a frequency of 8KHz, so the first The frequency of the clock signal is 8 times that of the second clock signal, and the frequency of the second clock is 256 times that of the frame ...
