In this paper, we suggest a QoS based OVPN framework depending on delay. Now-a-days QoS assurances by the service provider network for Optical Virtual Network (OVPN) over GMPLS/DWDM network are a demanding factor for telecommunication clients. The proposed framework computes wavelength dependent delay for all possible OVPN connections for a source and destination pair of a client and finally setup...
Advances in applications demanding high data rate wireless applications and existing wireless system upgrading has lead to scarcity in spectrum. Unlicensed new technologies like Digital video broadcast (DVB), Digital audio broadcast (DAB), internet, WiMAX etc. launched recently are reaching thousands of customers at rapid speed. Most of the primary spectrum is assigned, so it is becoming very difficult...
In this paper, we applied genetic algorithm (GA) scheme as a suboptimal detection of a bit-synchronous code division multiple access (CDMA) systems over a Gaussian channel. The GA scheme attempts to search for the user's transmitted bit sequence that optimizes the correlation matrix employed. Simulation results showed that the Bit Error Rate (BER) performance of our proposed multiuser detector is...
This paper presents the application of wilcoxon machines learning technique for artificial neural network in channel equalization application. The equalizer mitigates the effect of co-channel interference, inter-symbol interference in the presence of additive white Gaussian noise (AWGN). The performance of this proposed Multilayer Perceptron Network equalizer trained with wilcoxon learning has been...
This paper presents a novel technique in channel equalization. A wireless communication system is affected by inter-symbol interference, co-channel interference in the presence of additive white Gaussian noise and also with burst noise, where burst noise is defined to be a series of finite-duration Gaussian noise pulses with fixed duration and Poisson occurrence times. Adaptive equalization techniques...
