“…The mean square value of RS-RLS algorithm is -14dB, whereas RS-Bhagyashri algorithm has MSE value less than -2dB. Moreover, the proposed hybrid technique out performs other hybrid techniques reported in literature [27,28] in Fig. 13 for mitigation of impulsive noise.…”

“…OFDM system affected by impulsive noise is implemented using the MATLAB platform. The performance of proposed hybrid technique is compared with those of already reported techniques in literature [27,28] in both AWGN and Rician channel. The parameters used in simulating the OFDM system are described in Table 3.…”

“…That is why MSE criterion is used to judge the performance of adaptive filters in proposed hybrid technique. While, MSE of RS-CCV hybrid technique reported in [28] is not compared in Fig.11, because CCV is a fixed filter that is based on a windowing method and no error criteria is used in it. So, in order to do a fair comparison MSE of hybrid techniques based on adaptive filters only are compared in Fig.…”

In this paper, a new hybrid technique employing RS (Reed Solomon) coding and adaptive filter for impulsive noise suppression in OFDM (Orthogonal Frequency Division Multiplexing) systems is presented. Adaptive filter creates a more accurate estimate of the original OFDM signal after impulsive noise cancellation. The residual impulsive noise is further mitigated by RS decoder in the second stage of proposed technique. Three members of adaptive filters family i.e. NLMS (Normalized Least Mean Square) algorithm, RLS (Recursive Least Square) algorithm and Bhagyashri algorithm are tested with RS decoder in the proposed hybrid technique. Furthermore, the results in terms of steady state MSE (Mean Square Error) reduction, BER (Bit Error Rate) improvement and SNR (Signal to Noise Ratio) enhancement confirm the effectiveness of the proposed dual faceted technique when compared with the recently reported techniques in literature.

“…Furthermore, in order to measure the capability of the proposed AINC algorithm for PLC channel infected by impulsive noise, we compare its performance with those obtained from other similar algorithms, including the impulsive noise compensation (INC) algorithm proposed by Zhidkov [21], and the composite comparison value (CCV) based filter proposed by Jia and Meng [22]. To further quantify the performance of our proposed algorithm, we simulate the noise reduction performance of the proposed method by measuring the average MSE between the received and transmitted signals.…”

“…However, the performance of the scheme is highly declined when it is applied to PLC channel, when the impulsive noise magnitude is raised, and when higher order modulation is used. In [22], a time-domain pre-processing mean filter namely composite comparison filter is proposed to detect and reject impulsive bursts over wireless channels. It is based on the estimation of impulsive noise statistics.…”

In this paper, we propose a novel estimation and decoding scheme for power-line communication (PLC) systems in impulsive noise environments. The proposed scheme is based on the turbo coding combined with adaptive noise compensation to reduce burst errors and multipath effects. For this purpose, the PLC channel and noise models are introduced, then, the turbo encoder/decoder are inserted in the mapper/demapper and the pilot insertion block for the sake of enhancing preliminary estimation of the transmitted orthogonal frequency division multiplexing signals. The proposed impulsive noise compensator is based on the estimation of the impulse bursts using a new blanking/clipping function, and on the estimation of the signal to impulse noise ratio and the peak to average power ratio. Simulation results illustrate that receivers with combined turbo coding and the proposed noise compensator drastically outperform existing receivers under impulsive noise. In comparison to some existing schemes, the proposed scheme reaches its perfect performance in a reduced 15-paths environment, when the bit error rate and mean square error performance are tested. The improvements in SNR performance are more than 16 dB for BPSK modulation and can reach 12-20 dB for 16-QAM modulation, when a high impulsive noise level is considered.
