Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEEE 802.11a in USA and ....etc

Abstract—A fundamental question in multihop wireless network protocol design is how to partition the network's transport capacity among contending flows. A classically “fair” allocation leads to poor throughput performance for all flows because connections that traverse a large number of hops (i.e., long connections) consume a disproportionate share of resources. However, naïvely biasing against longer connections can lead to poor network utilization, because a significantly high fraction of total connections are long in large networks w ....etc

Pulse Shape Improvement in Core-Type High-Voltage Pulse Transformers With Auxiliary Windings
High-voltage pulsed power technologies are rapidly emerging as a key to efficient and flexible use of electrical power for many industrial applications. One of the most important elements in high-voltage pulse-generating circuit technology is the transformer, generallyused to further increase the pulse output voltage level. However, its nonideal behavior has significant influence on the output pulse shape.The most attractive winding configurati ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional ....etc

ABSTRACT

In this paper a new single phase to three-phase converter for ac motor is proposed. The proposed converter employs only six switches and incorporates active input current haping feature, which results in sinusoidal input current at close to unity power factor. The front-end rectifier in the proposed converter permits bidirectional power flow and therefore provides for excellent regulation against fluctuations in source voltage. This feature also facilitates regenerative braking of ac motor drive. An easy to implement control stra ....etc
