Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There are many condition monitoring methods such as vibration monitoring, thermal monitoring, chemical monitoring and acoustic emission monitoring. But all of these monitoring methods require expensive sensors and specialized tools. However, the condition monitoring method and fault diagnosis based on motor current signature are a better option since they do not require additional sensors. In this research, a novel criterion function of wavelet processing signal is introduced to diagnose the broken rotor bars in three-phase squirrel cage induction motors. This criterion function facilitates the precise diagnosis of the faults in induction motors under load variations. It uses wavelet transforms available in LabView software to process the stator current signals in the faulty induction motors to extract the wavelet coefficients in a specific time-frequency bands. Furthermore, spectrum analysis of the stator currents around the fundamental frequency is used to diagnose the faults. It is shown that the amplitudes of the frequency harmonics components fb=fs(1±2s) are influenced by the number of broken rotor bars, the exact location of broken rotor bars and the motor loading condition. 104 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A key part of wireless communication system is the Digital Down Converter (DDC). It can be performed by a dedicated hardware in a processor. For example, when a GSM module is activated and connected to the internet via WLAN, It can be reconfigured in the chip which is used for the DDC to execute a lot of tasks. In this case the hardware has a high utilization factor. The algorithm can be performed continuously and only parameter settings might be changed. Any adaptability and spare performance will not be used in this situation Currently radio frequency (RF) transceivers demand a high integration devices as well as low cost and low power operations. The system is able to adapt into multiple communication standards such as software defined radio (SDR). 120 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The design and implementation of capable constructing a new structure of RBF network equalizer based coded-OFDM. The importance of this design is to develop the conventional OFDM using channel estimator to compensate for the intersymbol interference (ISI) which suffers from multipath propagation and time varying channel, especially with mobile communication. The proposed structure solves the time-varying multipath signal propagation problem using equalization at the receiver. This requires and uses the channel coding to further protect transmitted data. Coded OFDM combined with channel equalization is considered the most effective means for a frequency selective fading channel. The research importance lies in using the radial basis function (RBF) network equalizer as a classification problem, where the idea is to map the received complex-valued signal into desired binary values. Results prove that the RBF network provides very good bit error rates with acceptable computational complexity. 96 pp. Englisch.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The power consumption in a communication system depends on the technology of the processor and the number of processing stages in decimation part. Programmability in the decimation filter, allows it to adapt to the different channel bandwidths, interferers requirements of the different standards, while maintained the power consumption at a minimum. The appearance of various standards in communication technologies in the world requires a good technique that able to provide a compatible standard replacing any part of the system by the software defined radio (SDR) technology. Digital down converter (DDC) filter is one of a typical type of data rate converter that could be used to satisfy the Software defined radio applications. The DDC decimation fitter require to design with full flexibility in terms of pass band ripple, adjacent band rejection and blocker requirements by optimizing the FIR filter design based on SDR concept. The main aim of this book is to design and implementation of the Digital Down Converter (DDC) filter with low pass band ripple and high attenuation in the adjacent rejection and blocker requirements in the filter response for Software Defined Radio(SDR).…
