Powerline Communication (PLC) Systems intents to use the mains network in vehicles for high-speed data
transmission. Carrier frequencies in the range of MHz are required to establish data rates of some megabits per second.
In this paper, typical reference channels extracted from channel measurements are presented and computation results of
their capacities according to Shannon’s theorem are presented. Furthermore, the effect of limitations of frequency
range and power spectral density of transmitted signal on achievable capacity is investigated. This ...

Low-density parity-check (LDPC) code is linear-block error-correcting code defined by sparse parity-check matrix. It is
decoded using the massage-passing algorithm, and in many cases, capable of outperforming turbo code. This paper
presents a class of low-density parity-check (LDPC) codes showing good performance with low encoding complexity.
The code is constructed using difference families from combinatorial design. The resulting code, which is designed to
have short code length and high code rate, can be encoded with low complexity due to ...
