Patent Searching and Data


Title:
TRANSMISSION CIRCUIT, TRANSMISSION EQUIPMENT AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2018046529
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To cancel the deviation of scrambled data to be generated.SOLUTION: In a transmission circuit 1, a transmission circuit 11 includes a transmission side data extraction circuit 31, a transmission side random pattern generation circuit 32, a diffusion calculation circuit 34 and a transmission data coupling circuit 36. The transmission side data extraction circuit 31 extracts data at a predetermined byte from the top of user data to be transmitted. The transmission side random pattern generation circuit 32 executes predetermined calculation processing, using an initial value which is determined from the data extracted by the transmission side data extraction circuit 31, to successively generate a transmission random pattern having a predetermined bit length. The diffusion calculation circuit 34 calculates the user data byte-by-byte with the generated transmission random pattern to generate transmission byte scrambled data. The transmission data coupling circuit 36 couples the generated transmission byte scrambled data with data extracted by the transmission side data extraction circuit, to generate transmission scrambled data.SELECTED DRAWING: Figure 7
