Abstract

In recent years, it is said that communication speed of next-generation cellular phones will reach 100Mbps. Accordingly, demand for robust error correction codes with high-speed processing is increasing. High-dimensional discrete torus knot code (torus code) performs well in fields with many errors. We propose a new and unique synchronization system that uses the torus code. It performs error correction and synchronization processing effectively and simultaneously. According to results of comparison with a conventional system (HDLC:High Level Data Link Control), performance (Loss of Lock Probability) of the proposed synchronization system is as much as 5 figures better than the conventional HDLC in the 10-4 field (Input BER). By applying a LSI technology, we have developed a FPGA(3Dm5, 125bit, r=0.512) with the proposed synchronization system and have built a high-speed MPEG communication device which uses the newly developed FPGA. The high-speed MPEG communication device can transmit a video signal of 20Mbps.
