摘要： Optical signals are transmitted across a rotary junction using an active optical rotary coupler. A rotary optical joint assembly includes a rotatable optical coupler and an optical signal processing system. The rotatable optical coupler aligns two optical fibers for optical communication across a rotary optical junction. The optical signal processing system includes a local optical transceiver that receives the signals and compensates for at least a portion of signal loss or other signal imperfections incurred from transmitting the signal across the rotary optical junction. The local optical transceiver also processes the signals for longer distance transmission.

摘要： A multi-mode multi-parallelism data exchange method and the device thereof are proposed to apply to a check node operator or a bit node operator. The proposed method comprises the steps of: duplicating part or all of an original shift data as a duplicated shift data; combining the original shift data and the duplicated shift data to form a data block; and using a data block as the unit to shift this data block so as to conveniently retrieve shift data from the shifted data block. With a maximum z factor circuit and duplication of part of data, specifications of different shift sizes can be supported. The functions of shifters of several sizes can therefore be accomplished with the minimum complexity.

摘要： An operating method applied to low density parity check (LDPC) decoders and the circuit thereof are proposed, in which original bit nodes are incorporated into check nodes for simultaneous operation. The bit node messages are generated according to the different between the newly generated check messages and the previously check node messages. The bit node messages can be updated immediately, and the decoder throughput can be improved. In the other way, the required memory of LDPC decoders can be effectively reduced, and the decoding speed can also be enhanced.
