Increasing Transmission Distance in THz systems with MDPC Code and Auxiliary Channel
share
We analyze whether multidimensional parity check (MDPC) code and an auxiliary channel can improve the throughput and extend the THz transmission distance. While channel quality is addressed by various coding approaches, and an effective THz transmission system configuration is enabled by other approaches with additional channels, their combination is new with the potential for significant improvements in quality of the data transmission. Our specific solution is designed to correct data bits at the physical layer by a low complexity erasure code (MDPC), whereby original data and parity data are simultaneously transferred over two parallel THz channels, including one main channel and one additional channel. The results are theoretically analyzed to see that our new solution can improve throughput, support higher modulation levels and transfer data over the longer distances with THz communications.
