Its analysis andnmodeling is relatively straightforward in linear analog circuits, suchnas amplifiers. For such circuits, the SPICE AC noise analysis is, mostnof the time, adequate for noise performance characterization. However,nfor communication circuits, where nonlinearities and frequencyntranslation ...
The article presents an innovative approach to increasing the number of digital samples in analog-to-digital systems using a strobing method in a “sliding-window” mode. Particular attention is paid to optimizing the in-phase/quadrature demodulation for signals with orthogonal frequency division multip...
above which it rolls off with approximately a first order lowpass response. Where this technique comes in handy is modeling non-flat noise floors, either due to higher order analog filtering, or active elements themselves
This book presents a novel approach to the analysis and design of all-digital phase-locked loops (ADPLLs), technology widely used in wireless communication devices. The authors provide an overview of ADPLL architectures, time-to-digital converters (TDCs) and noise shaping. Realistic examples illustr...
Phase noise is a concern for all radio systems, but radar in particular can require phase noise performance at frequency offsets much closer to the carrier than a communication system.
Without some real-time control of the pointing angle, these highly directional antennas may not be able to support continuous communication while experiencing this type of inertial motion. Figure 1. Example of a motion control system architecture. The system in Figure 1 uses a servo motor, which...
An example of zero-mean white Gaussian noise with a variance of σn2 = 0.25 is shown in Figure 3.3(b). Even if this assumption may not hold in certain cases, it does help make the mathematical analysis of digital communication systems tractable. The receiver has to make a decision on ...
