The objective of the proposed approach is to extract useful signals from background noise. This paper describes the adaptive detection of an unknown signal in a colored noise background. In the proposed technology, the ability for the self-adaptive neural network fuzzy inference system (ANFIS ) approaching the nonlinear function is used. First, the nonlinear dynamic characteristic of colored noise...
Noise detecting and elimination is important for data acquisition of impact drilling stress wave. ANN (Artificial Neural Network) is provided with stronger fault-tolerance and redundancy. And ANN takes on good robustness for data errors. Therefore, a new method, ANN methods, is put forward on processing ldquoburrrdquo phenomena (noise signal) for data acquisition of impact drilling stress wave. The...
Signal quantization levels can have significant impact on the performance of a GPS receiver, especially in the present of the interference. In this paper, signal quantization model for estimating interference suppression of the correlator output and evaluating the performance of GPS receiver is presented. With the proposed model, performance of the receiver in acquisition process is demonstrated by...
The performance analysis of the zero-forcing successive interference cancellation (ZF-SIC) detector in vertical Bell labs layered space-time (V-BLAST) is generally considered under additive white Gaussian noise (AWGN) channel. However, a large class of physical phenomenon observed in wireless systems exhibit non-Gaussian behavior. In this paper we present the performance of the (V-BLAST) detection...
In this paper we present a new method of compensating for complex multipath channel fading in blind multiuser detection for DS-CDMA communication. This compensation allows for the use of different chip pulse shapes. The compensation is based on the incorporation of priors derived from the FFT of the pulse shape. The system employs detectors that incorporate methods of independent component analysis...
