The partial rake receiver (PRR) is analyzed in the presence of fading and impulsive noise. The maximum likelihood PRR for impulsive, fading channel is derived, and a suboptimum PRR with reduced complexity is obtained. It is shown from numerical results that, when the noise is impulsive, the PRRs designed for impulsive noise offer performance improvement over those optimized for Gaussian environ...

This paper proposes an new iterative method to recover the signals corrupted by impulsive noise in MIMO-OFDM systems over In-home PLC. In this iterative technique, preliminary decisions are made to get the impulsive noise detection algorithm for finding the locations and amplitudes of the impulses, and then signal estimation block for approximation the signals for two-branch 2*2 MIMO-OFDM at th...

This paper addresses the estimation of carrier frequency for cyclostationary AM, BPSK, and QPSK signals in the presence of interfering signals and α-stable impulsive noise. The performance of conventional DFT algorithms suffers from severe degradation in impulsive noise environments. By fusing cyclostationarity and fractional lower-order statistics, we introduce a signal selective carrier frequ...

This paper addresses the problem of impulsive noise cancellation in digital signal area. The myriad and meridian filters are the type of robust filters which are very useful in suppressing the impulsive type of noise. The cost functions of theses filters have very similar structure. In this paper the generalized filter based on Lp norm is presented. The proposed filter operates in a wide range ...

The performance of DMT systems is studied in impulsive noise channels by using Middleton's Class A noise distribution. A statistical model is developed to generate Class A distributed impulsive noise samples and this model is used for the performance analysis. An exact expression is derived for the subchannel SER. By employing the central limit theorem, the subchannel SER is further simplified....

Multi-Input Multi-Output (MIMO) receivers have been typically designed and their communication performance studied in the presence of additive white Gaussian noise. While this is an accurate model for the thermal noise present at the receiver, it falls short of modeling the radio frequency interference (RFI) that may affect the transceivers. RFI is a combination of independent radiation events ...

A novel impulsive noise elimination filter, entitled noise exclusive filter (NEF), which shows a high performance at the restoration of images distorted by impulsive noise, is proposed in this paper. NEF uses chi-square goodness-of-fit test in order to detect the corrupted pixels more accurately. Simulation results show that the proposed filter achieves a superior performance compared with the ...

A new impulsive noise removal filter, adaptive dynamically weighted median filter (ADWMF), is proposed. A popular method for removing impulsive noise is a median filter whereas the weighted median filter and center weighted median filter were also investigated. ADWMF is based on weighted median filter. In ADWMF, instead of fixed weights, weightages of the filter are dynamically assigned with th...

In this paper, we investigate the effects of impulsive noise on the DS/SSMA systems using TCM. We obtain the probability of bit error bound of the systems, considering both impulsive noise and Rician fading unavoidable in mobile communication environments. It turns out that we can achieve some coding gain by using TCM under impulsive noise environment at moderate to high signal to noise ratio (...
