“…It is shown that the performance of the DE-based construction is better than the heuristic method, which achieves 0.5 dB gain for N = 1024 at FER = 10 −4 and greatly lowers the error floor for N = 256. In addition, the derived theoretical BLEP in (12) accurately predicts the simulated performance. Furthermore, we observe that when the block length is short (N = 256), a severe error floor is present even with optimal LLR values.…”

“…Following the updated equations of DE, the error probability of the decoder can be obtained. Hence the BLEP of polar codes with OFDM can be obtained by using (12). We note that this BLEP is an approximation of the exact BLEP since we assume Z k is Gaussian distributed.…”

“…In particular, LDPC codes have been adopted in the G.hn/G.9960 standard for PLC. Recently, polar codes have been employed to mitigate impulsive noise and shown comparable performance to LDPC codes but with lower complexity [11][12][13]. However, the polar codes used in the literature were only constructed using the unoptimized heuristic construction method which leads to a sub-optimal performance.…”

In this paper, density evolution-based construction methods to design good polar codes on impulsive noise channels for single-carrier and multi-carrier systems are proposed and evaluated. For a single-carrier system, the tight bound of the block error probability (BLEP) is derived by applying density evolution and the performance of the proposed construction methods are compared. For the multi-carrier system employing orthogonal frequency-division multiplexing, the accurate BLEP estimation is not feasible so a tight lower bound on the BLEP for polar codes is derived by assuming the noise on each sub-carrier is Gaussian. The results show that the lower bound becomes tighter as the number of carriers increases.

“…Also, different hamming codes like turbo codes, LDPC codes and polar codes are used to cancel errors over PLC channel. Polar codes can achieve the Shannon capacity and their performances are investigated in [8] to mitigate impulsive noise. Moreover, polar codes designed by Arikan [9] are evaluated in our simulations since they can achieve Shannon capacity.…”

Future wireless communication systems will consist of multiple networks with various capabilities. Wireless networks may encounter severe distortions due to the presence of interfering signals generated at some power stations dedicated to smart grid applications. In fact, severe environmental effects of high voltage substations must be considered, particularly impulsive noise needs to be taken into account. Firstly, to cope with this kind of hostile environment, an efficient channel coding scheme in a mono-user system is proposed, when one source user transmits data directly to one terminal user. Performance analysis shows that the proposed coding schemes based on rank metric codes are very efficient to eliminate impulsive noise in mono-user mode. Furthermore, this approach are expanded in order to show the efficiency of rank codes in Wireless Sensors Networks (WSNs), when considering the problem of collecting data in WSNs in the presence of impulsive noise errors together with AWGN channel. To increase the reliability of the system, an advanced Network Coding technique (NC) is applied based on LRPC (Low Rank Parity Check) codes which exhibits noteworthy performances.

“…PC were presented with the successive cancellation (SC) decoder which can be considered as a fairly low complexity decoder. In the context of PLC, the authors in [20] have recently investigated the performance of PC over PLC channels with the help of the signal level limiter. However, this study consider only single-carrier scenario.…”

The performance of power line communication (PLC) systems suffer mainly from non-Gaussian noise, commonly referred to as impulsive noise. To reduce the effect of this noise, various channel coding techniques have been studied in the literature over PLC channels. Unlike existing works, in this paper we investigate the performance and robustness of polar codes over impulsive noise PLC channels for different codeword lengths and noise scenarios in orthogonal frequency division multiplexing (OFDM) systems. In particular, insightful comparisons between hard decision (HD) decoding and soft decision (SD) decoding for the proposed system are made. Furthermore, we investigate the blanking and clipping techniques with polar codes for impulsive noise mitigation. In addition, for the sake of comparison, results for LDPC coding are also presented. The results show that polar codes can considerably improve the performance of PLC systems. It will also be demonstrated that SD decoding offers better performance than HD decoding and that as the codeword length is increased, the performance can be further improved.
