چکیده

The transmission over the memoryless additive white Class-A noise (AWCN) channel is considered. For uncoded transmission, an exact expression for the symbol error rate is derived. For coded transmission, the Chernoff bound on the pairwise error probability is calculated and the performance achieved on the real and the complex AWCN channels is compared. Moreover, a lowcomplexity, suboptimum decoding metric is derived and analyzed employing the cutoff rate as a performance criterion.

Detection of Weak Signals with Partial Rake Receivers in Impulsive Interference Environment

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...

Optimum Detection of M-ary Orthogonal Signals in ELF Noise Environments

Explicit receiver structures for the optimum detection of M-ary orthogonal signals in impulsive noise environments typical of ELF are determined. The resulting optimum structures, while shown to bear some resemblance to that which would have been obtained in the presence of Gaussian noise alone, exhibit an interesting nonlinear behavior. The difficulties in the actual implementation of this rec...

Successive interference cancelation for a CDMA system with diversity reception in non-Gaussian noise

A large class of physical phenomenon observed in practical wireless systems exhibits non-Gaussian behavior. The performance of many multiuser detectors can degrade substantially in the presence of such impulsive ambient noise. In this paper, multiuser detection of space coded MIMO and code division multiple access (CDMA) signals under impulsive noise with diversity reception are investigated. W...

A Robust Distributed Estimation Algorithm under Alpha-Stable Noise Condition

Robust adaptive estimation of unknown parameter has been an important issue in recent years for reliable operation in the distributed networks. The conventional adaptive estimation algorithms that rely on mean square error (MSE) criterion exhibit good performance in the presence of Gaussian noise, but their performance drastically decreases under impulsive noise. In this paper, we propose a rob...

OFDM Transmission Corrupted by Impulsive Noise

OFDM is a promising technique being used for bandwidth efficient communication over the power-line channel. It provides excellent possibilities to adapt to the frequency-selectivity of the channel. The influence of impulsive noise on the OFDM transmission is not well analyzed yet. We choose Middletons Class A man-made noise model to statistically describe the impulsive interference and study th...
