Abstract

The invention relates to the technical field of common public radio interface CPRI optical fiber transmission, especially a parallel scrambling device and a parallel scrambling method. The device comprises a parallel scrambling code generator, a selection judger and an exclusive or arithmetical unit; the output end of the parallel scrambling code generator is connected to the input end of the selection judger; the output end of the selection judger is connected to the input end of the exclusive or arithmetical unit; the parallel scrambling code generator is used for generating M scrambling codes in K clock cycles; every scrambling code comprises N digits; the K is an positive integer; the M is an positive integer; the N is an positive integer. According to the device, the M scrambling codes is generated in K clock cycles by the parallel scrambling code generator; every scrambling code comprises N digits, namely (M *N) / N-digit scrambling codes are generated in one clock cycle; the digits of the scrambling codes generated in one clock cycle are increased; the working frequency of the scrambling code generator is reduced under the condition that the scrambling codes are sent at the same rate; and therefore, the device cost and related difficulty are reduced.

Description

technical field [0001] The present application relates to the technical field of CPRI optical fiber transmission, in particular to a parallel scrambling device and a parallel scrambling method. Background technique [0002] Due to the rapid development of mobile communication, the increase of 2G, 3G, and 4G air interface bandwidth will inevitably lead to an increase in the amount of data processed and transmitted within mobile communication equipment, thus affecting the BBU (Building Base band Unit, baseband processing unit) + RRU (Radio Remote Unit, radio frequency remote unit) fiber optic transmission between put forward higher requirements, then the transmission rate of CPRI (Common Public Radio Interface, general public radio interface) also from the initial 614.4Mbit / s, 1228.8Mbit / s etc. Soared to 9830.4Mbit / s or even higher. In order to transmit high-speed data more reliably, it is recommended to use scrambling to improve the reliability of the transmission system whe...
