%
% inputs:
% sig2 - noise variance
% Mt - number of Tx antennas
% Mr - number of Rx antennas
% x - vector of complex input symbols (for MIMO, this is a matrix, where each column
% is the value of the antenna outputs at a single time instance)
% H - frequency selective channel - represented in block-Toeplitz form for MIMO transmission
% N - number of symbols transmitted in OFDM frame
%
% outputs:
% y - vector of channel outputs (matrix for MIMO again, just like x matrix)
% create noise vector sequence (each row is a different antenna, each column is a
% different time index) note: noise is spatially and temporally white
This book is the culmination of more than 20 years of building, studying, and teaching real-time systems. The author’s travels have taken him to NASA, UPS, Lockheed Martin, the Canadian and Australian Defense Forces, MIT’s Charles Stark Draper Labs, and many other places. These visits and interactions with literally hundreds of students from such places as Boeing, Motorola, and Siemens have resulted in a wider understanding of real-time systems and particularly their real application. This book is, in essence, a compendium of these experiences. The author’s intent is to provide a practical framework for software engineers to design and implement real-time systems. This approach is somewhat different from that of other texts on the subject.
an analysis software with souce code for the time series with methods based on the theory of nonlinear deterministic dynamical systems, or chaos theory.這套軟件源碼是根據H. Kantz and T. Schreiber, ``Nonlinear Time Series Analysis , Cambridge University Press, Cambridge (1997).
Space-Time Processing for CDMA Mobile Communications.Written for research students and design engineers, this book addresses many basic questions related to the use of space-time processing in CDMA-based third-generation systems
