“…Different strategies have been proposed to mitigate the impulsive noise. One of the strategies is the nonlinearity technique which includes clipping nonlinearity [8], [9]; blanking nonlinearity [10]; and combined blanking-clipping [11], [12]. The performance of OFDM receivers with the nonlinearity impulsive noise mitigation techniques of blanking, clipping, and combined blanking-clipping has been compared in [13].…”

This paper presents a novel approach to mitigate the periodic impulsive noise before the synchronization of the orthogonal frequency-division multiplexing (OFDM)-based power-line communications (PLC) system. The proposed algorithm is employed to detect the periodic impulsive noise and then suppresses the periodic impulsive noise with an adaptive infinite impulse response (IIR) notch filter before the synchronization of the system, finally compensating the distortion of received signals brought by the IIR notch filter. Subsequently, the periodic impulsive noise mitigation algorithm is simulated and implemented in the PLC receiver's physical layer. Finally, the proposed algorithm is verified in field-programmable gate array and tested in the indoor PLC network. The simulation and field trial results show that the proposed periodic impulsive noise mitigation technique is simple and effective for the narrowband OFDM-based PLC system, such as the application of automatic meter reading.Index Terms-Adaptive infinite impulse response (IIR) notch filter, compensation, detection, orthogonal frequency-division multiplexing (OFDM), periodic impulsive noise, power-line communications (PLC).

“…With maximizing the signal-to-interference-and-noise ratio (SINR) criterion, an adaptive blanking threshold for the OFDM receiver is also proposed in [8]. To eliminate the ICI caused by pulse blanking, an iterative reconstructing and subtracting ICI method is proposed in [9,10], and a frequency-domain ICI compensation scheme based on finite impulse response equalizer is proposed in [11].…”

Pulse blanking is a widely used method to eliminate impulsive interference in an orthogonal frequency division multiplexing (OFDM) receiver. To analyze the effect of the inter-carrier interference caused by pulse blanking on the symbol error rate (SER) performance of OFDM employing maximum ratio combining (MRC) receiver, the analytical expression of the signal-to-interference-noise ratio (SINR) of the OFDM employing MRC receiver is derived. Based on the SINR expression, furthermore, the SER performances over both Rayleigh and Ricean fading channels are also analyzed quantitatively. Simulation results validate the correctness of the derived formulas.

Previous research developed an asymptotic performance limit (APL) of a multistage parallel interference cancellation (PIC) scheme. However, the derivation was very complex. This study derives a closed form of the APL of a multistage PIC, in which z transformation is used in a new, simple technique to compute the APL. We also derive a closed-form expression of maximum user capacity. The results of the analysis show that this new technique could be used to derive the APL.
