论文 通过提高保证成本的状态延迟控制和量子自适应控制的一台四轮直升机的控制策略
Improved guaranteed cost control and quantum adaptive control are developed in this study for a quadrotor helicopter with state
delay and actuator faults. Improved guaranteed cost control is designed to eliminate disturbance effects and guarantee the robust stability of a
quadrotor helicopter with s ...
书籍 OFDM+Baseband+Receiver+Design
All wireless communication standards, existing and under development, adopt or
consider adopting orthogonal frequency-division multiplexing (OFDM) as the
modulation technique. It is clear that OFDM has become the definitive modulation
scheme in current and future wireless communication systems.
书籍 Spectrum+Access+and+Management
The radio spectrum is one of the most precious resources which must be managed
to ensure efficient access for the wireless communication services which use it. The
allocation and management of spectrum are administered by the regulatory
authorities. Traditionally, spectrum allocation is carried out ...
书籍 Wavelength Division Multiplexing
Wavelength division multiplexing (WDM) refers to a multiplexing and transmission
scheme in optical telecommunications fibers where different wavelengths, typically
emitted by several lasers, are modulated independently (i.e., they carry independent
information from the transmitters to the receivers) ...
书籍 Fundamentals_of_Global_Positioning_System1
The purpose of this book is to present detailed fundamental information on a
global positioning system (GPS) receiver. Although GPS receivers are popu-
larly used in every-day life, their operation principles cannot be easily found
in one book. Most other types of receivers process the input signals ...
