Embodiment Construction
[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0025] figure 1 It is a flowchart of a method for delimiting symbols of parallel data according to an embodiment of the present invention, such as figure 1 As shown, the method mainly includes the following steps (step S102-step S106):
[0026] Step S102, cutting and splicing the undelimited parallel data to obtain a set of undelimited parallel data streams with the same width;
[0027] Step S104: Perform delimiter detection on each undelimited parallel data stream, and when a frame header delimiter is detected at a predetermined position of one of the undelimited parallel data streams, it is determined that the delimitation is successful, and the detected frame header delimiter is obtained. The d...

The invention discloses a method and device for delimiting symbols of parallel data. The method includes: cutting and splicing undelimited parallel data to obtain a set of undelimited parallel data streams with the same width; performing delimiter detection on each unbounded parallel data stream; When the frame header delimiter is detected at the predetermined position of the stream, it is determined that the delimitation is successful, and the delimited channel number of the channel where the detected frame header delimiter is located is obtained, wherein each channel passes through an undelimited parallel data stream; according to The delimited channel number converts the undelimited parallel data stream into delimited parallel data, wherein the width of the delimited parallel data is an integer multiple of the width of the frame header delimiter. The invention can achieve the effect of completing symbol delimitation from parallel data with different widths of symbols and containers, and recovering the stream of symbols determined by the bit boundary.
Description
technical field [0001] The present invention relates to the field of communication, in particular to a method and device for delimiting symbols of parallel data. Background technique [0002] The CPRI (Common Public Radio Interface, common public radio interface) protocol aims to define a public interface between a REC (Radio Equipment Control, radio equipment control center) and an RE (Radio Equipment, radio equipment). The L2 fast control and management channel (Fast C&M Channel) in this protocol supports Ethernet packet transmission and is used for sending and receiving operation and maintenance messages between the REC and the RE. The 4B / 5B encoded Ethernet code group stream, user data and other control words are transmitted in the CPRI interface in a time-division multiplexed manner. [0003] The container used to transmit the Ethernet code group in the CPRI frame format is in units of bytes, and the Ethernet data is in units of 10 bits. Therefore, after the Ethernet c...
