Error Correction with Systematic RLNC in Multi-Channel THz Communication Systems
The terahertz (THz) frequency band (0.3-10THz) has the advantage of large
available bandwidth and is a candidate to satisfy the ever increasing mobile
traffic in wireless communications. However, the THz channels are often
absorbed by molecules in the atmosphere, which can decrease the signal quality
resulting in high bit error rate of received data. In this paper, we study the
usage of systematic random linear network coding (sRLNC) for error correction
in generic THz systems with with 2N parallel channels, whereby N main
high-bitrate channels are used in parallel with N auxiliary channels with lower
bit rate. The idea behind this approach is to use coded low-bit rate channels
to carry redundant information from high-bit rate channels, and thus compensate
for errors in THz transmission. The analytical results evaluate and compare the
different scenarios of the THz system in term of the amount of coding
redundancy, a code rate, transmission rate of auxiliary channels, the number of
THz channels, the modulation format and transmission distance as required
system configurations for a fault tolerant THz transmission.Comment: 6 pages, 5 figure
