Abstract: This article examines the performance of coded OFDM Power Line Communications (PLC) systems based on two channel scenarios: the standard model and the actual channel. The study utilizes a bottom-up methodology, initially focusing on the traditional model. Next, we evaluate the system's performance in relation to the physical characteristics of the channel, such as the network topology, cables, and loads. As a method that works well in PLC systems, we use low-density parity-check (LDPC) codes, especially when there needs to be little delay and the best use of the available frequency spectrum. Then, it identifies the impact of iteration and trade-off with the required BER for both channel scenarios and applies a simple mitigation method for impulsive noise (IN). The conducted simulations yielded findings that demonstrated the system's ability to reach its maximum capacity, even in the face of sporadic bursts of impulse noise. The analysis shows that typical LDPC codes can achieve a favorable balance between spectral and energy efficiency when they employ appropriate coding schemes. Furthermore, these codes are able to meet the specified latency restriction without any compatibility issues. [ABSTRACT FROM AUTHOR]
