These criteria have most commonly been applied to space-time codes in the more restrictive sense, but they also apply to MIMO schemes such as spatial multiplexing and precoding. In the generalized sense, a space-time code is the generalization of a conventional code such as a Forward Error ...
This thesis has two main contributions: the designs of differential/non-differential unitary space-time codes for multiple-antenna systems and the analysis of the diversity gain when using space-time coding among nodes in wireless networks. Capacity has long been a bottleneck in wireless communications...
SPACE-TIME CODE DESIGN FOR FADING CHANNELS A method, and associated apparatus, for a sending station operable in a communication system, such as a cellular communication system. A codeword is formed which, when transmitted upon a channel, exhibits a selective level of space and t... IONESCU ...
Space time block coding is a modulation scheme recently discovered for the transmit an- tenna diversity to combat the effects of wireless fading channels. ... X Feng,D Yue - 《电子科学学刊(英文版)》 被引量: 12发表: 2007年 MIMO OFDM-CDMA system with pilot tone and space-time block codin...
Space-time codes for wireless optical communications A space-time channel coding technique is presented for overcoming turbulence-induced fading in an atmospheric optical heterodyne communication system that ... SM Haas,JH Shapiro,V Tarokh - Hindawi Publishing Corp. 被引量: 106发表: 2002年 Asymmetric...
Attackers have access to debuggers, and they have both the time and the knowledge to determine exactly how these systems work—and often break them in a matter of hours. Rather, you should use the CryptoAPI for Win32® applications, and the System.Security.Cryptog...
XAML has very intimate ties with the Avalon class library: every element type you can use in XAML is actually a class and, specifically, a descendent of the UIElement or ContentElement classes declared in the MSAvalon.Windows namespace. Among the descendents of UIElement is Control, from whic...
Build and formatPress ctrl-space to build or export the current file. Press ctrl-w to format the current file, in an opinionated way. If the current file is empty, a "Hello, World!" template will be inserted, for some file extensions. If a build or export returns an error code and ...

Instead, code should use the System.Security.Cryptography namespace or use Win32 encryption such as Data Protection Application Programming Interface (DPAPI). Review the following questions to help identify potential cryptography related vulnerabilities:...
