In this study, the performance of the proposed receiver with the neural network Multiple Access Interference (MAI) detector is compared with the matched filter bank (classical receiver), neural network that detects user's signal and single user bound for Additive White Gaussian Noise (AWGN) and Rayleigh fading asynchronous channels by computer simulations. There are a lot of study in the litera...

We consider the problem of uniform error property (UEP) for a coded modulation with constant energy multidimensional symbols, transmitted over the additive white Gaussian noise (AWGN) or fading channels and received by a broad class of decoders. This class includes coherent, partially coherent, double differential, and noncoherent decoders, decoders designed for fading channels, decoders using ...

For the simple binary detection problem of detecting a known signal in the presence of additive noise, the matched.filter is well known to yield the highest output signalto-noise ratio (SNR). When the detection is carried out in discrete time, selecting an optimal Jilter length for a speciJc detection problem is important. Bounds on the SNR of the matched filter can assist in this selection. Ex...

This paper mainly deals with the problem of target detection in the presence of Compound-Gaussian (CG) clutter with the Inverse Gaussian (IG) texture and the unknown Power Spectral Density (PSD). The traditional CG distributions, in particular the K distribution and the complex multivariate t distribution, are widely used for modeling the real clutter data from the High-Resolution (HR) radars. ...

Conclusion: We have derived new expressions for the symbol error rate performance of coherent M-ary phase shift keyed signals in slow nonselective Nakagami fading and additive white Gaussian noise channel. For integer values of the Nakagami fading parameter m, a closed-form expression is derived for the symbol error rate. However, for real values of nz, a simple formula which can be easily comp...

The recent and rapid evolution of wireless technologies has led to a high demand in terms of resources. To solve this prob-lem the idea of cognitive radio has been introduced to facilitate a good spectrum management and efficient use of the spectrum. In this article, a method for the detection of the spectrum with the purpose of detecting the presence of bands of unoccupied frequencies is propo...

This paper analyzes the performance of the linear parallel interference cancellation (LPIC) multiuser detector in a synchronous multiuser communication scenario with binary signaling, nonorthogonal multiple access interference, and an additive white Gaussian noise channel. The LPIC detector has been considered in the literature lately due to its low computational complexity, potential for good ...

The prefrontal cortex exerts top-down influences on several aspects of higher-order cognition by functioning as a filtering mechanism that biases bottom-up sensory information toward a response that is optimal in context. However, research also indicates that not all aspects of complex cognition benefit from prefrontal regulation. Here we review and synthesize this research with an emphasis on ...

This paper considers the generic problem of detecting in the presence of additive noise, which one from a set of known signals has been received. In place of the classical matched #lter (MF) receiver we propose a modi#ed receiver. When the transmitted signals are linearly independent this receiver is referred to as an orthogonal matched #lter (OMF) receiver, and when the transmitted signals are...
