Everyday final applications of measurement processes are mostly aimed at making a decision, on the basis of comparison between the measurement result and a threshold, which could be a single numerical value or another measurement result. Of course, the latter case is the more general one since the single-value threshold is, from a metrological point of view, a measurement result with zero associated uncertainty or, more specifically, a measurement result whose associated uncertainty is much lower or negligible, with respect to the uncertainty associated to the other measurement result....

This book presents a general overview on the concept of MIMO OFDM for communication systems. Moreover, the different detection schemes for such systems are portrayed with special emphasis on the LS, ZF & LMMSE detector. The core of a LMMSE detector requires matrix inversion, which is usually regarded as a computationally intensive task. Hence, the CORDIC and SGR algorithms that can be used to decrease the complexity of matrix inversion are explored in depth and their software and hardware implementation issues are analyzed. The goal of this thesis is to realize an implementation of the LMMSE...

The purpose of this Book is to provide a better communications systems for the Robo soccer robots. The soccer robots are required to obtain commands from a host computer. The host computer is connected to an overhead camera that determines the location of robot and balls on the field. The host computer then makes use of a multi-agent planning system (MAPS) to determine the actions that the robots should take. These actions and the position of the robot and balls are transmitted to the robot via a wireless transmitter connected to the serial port of the host computer and receivers connected to...

This book basically gives the over view about The properties of erbium-doped fiber amplifier (EDFA) such as gain and noise figure have been studied. By determining the characteristics of the 980nm, 1480nm & 1550nm laser sources and ASE (amplified spontaneous emission) at the output of the amplifier used to determine the gain and noise figure of EDFA. This model allows to follow the signal (1550nm), pump (980nm) and ASE as they propagate along the fiber and determine population inversion .The both forward and backward propagation ASE are important in determining the overall gain and noise...

In this book, various three level PWM control topologies are discussed in detail and simulations are carried out. It is demonstrated that the input current is sinusoidal and the input power factor is almost unity. Capacitor voltage balancing is also achieved. The concept of Non-dissipative snubber is introduced and a "Soft-Switched Single-Phase Three-Level Rectifier" using passive lossless snubber is analyzed in detail and PSIM simulation is carried out to investigate its performance.
