Performance of Coded Multi-Line Copper Wire for G.fast Communications in the Presence of Impulsive Noise

In this paper, we focus on the design of a multi-line
copper wire (MLCW) communication system. First, we construct
our proposed MLCW channel and verify its characteristics based
on the Kolmogorov-Smirnov test. In addition, we apply Middleton
class A impulsive noise (IN) to the copper channel for further
investigation. Second, the MIMO G.fast system is adopted utilizing
the proposed MLCW channel model and is compared to a single
line G-fast system. Second, the performance of the coded system
is obtained utilizing concatenated interleaved Reed-Solomon (RS)
code with four-dimensional trellis-coded modulation (4D TCM), and
compared to the single line G-fast system. Simulations are obtained
for high quadrature amplitude modulation (QAM) constellations
that are commonly used with G-fast communications, the results
demonstrate that the bit error rate (BER) performance of the coded
MLCW system shows an improvement compared to the single line
G-fast systems.
