摘要

#CMT# #/CMT# The device (DDC) has multiplexers with elemental inputs respectively coupled to two inputs taken among n number of inputs (E1-EN) in a manner not shifting multimode data (W1-WN) presented on elemental inputs of a shifting elemental value depending on altitude of a shifting stage, and a shifting direction is identical for the multiplexers of a configurable shifting circuit. A control unit (MCI) controls the different multiplexers to deliver R input data on R number of predetermined outputs (S1-SN) regardless of total value of desired shifting smaller than R. #CMT#USE : #/CMT# Device for electronically shifting multimode data for coding and decoding with a low density parity check code, by a channel coding device and a channel decoding device (all claimed), for performing cyclic permutation of input data in a field of operating system based on a wireless transmission standard such as IEEE 802.16eintended to fixed and mobile broadband wireless access systems and IEEE 802.1intended to local and metropolitan networks, and field of satellite transmission based on the standard of digital video broadcasting (DVB) 52. #CMT#ADVANTAGE : #/CMT# The configuration of the device reduces the encumbrance of the device, avoids the sorting problem of data and reconfiguration of the device. The configuration of the device reduces the number of multiplexers. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a data shifting device.
