ApplicationsoftheKalmanFilterslgorithmtorobotloca - To model the robot position we wish to know its x and y coordinates and its
orientation. These three parameters can be combined into a vector called a state
variable vector. The robot uses beacon distance and angle measurements and
locomotion information about how far it has walked to calculate its position. As with
any real system, these measurements include a component of error (or noise). If
trigonometry is used to calculate the robot s position it can have a large error and
can change significantly from frame to frame depending on the measurement at the
time. This makes the robot appear as if it is "jumping" around the field. The Kalman
Filter is a smarter way to integrate measurement data into an estimate by
recognising that measurements are noisy and that sometimes they should ignored
or have only a small effect on the state estimate.,2010-07-08 02:31:13,下载9次
kalmanintroduction.rar - In his 1960 famous publication (“A new approach to linear filtering and prediction problems”, Trans.ASME J. Basic Engineering., vol 82, March 1960, pp 34-45), Rudolf Kalman based the construction of the state estimation filter on probability theory, and more specifically, on the properties of conditional Gaussian
random variables. The criterion he proposed to minimize is the state vector covariance norm, yielding to the classical recursion : the new state estimate is deduced from the previous estimation by addition of a correction term proportional to the prediction error (or the innovation of the measured signal).,2010-07-08 02:26:01,下载7次
Channel_Codes.rar - This book includes BCH codes, Reed–Solomon codes, convolutional codes, finite-geometry
codes, turbo codes, low-density parity-check (LDPC) codes, and product codes.
However, the title has a second interpretation. While the majority of this book is
on LDPC codes, these can rightly be considered to be both classical (having been
first discovered in 1961) and modern (having been rediscovered circa 1996),2010-07-08 02:20:16,下载27次
UW_RPC.rar - Among the most recent
innovations in this field, the scientific community is particularly interested
in ultra-wideband (UWB) technology. This technique consists of transmitting
radio signals spreading over very large frequency bandwidths, typically in the
order of 500 MHz to several GHz. Initially developed in the field of radar
localization, UWB technology is now seen as a promising candidate for future
wireless transmission systems.,2010-07-08 01:53:32,下载5次
