MIMO identical eigenmode transmission system (IETS) - A channel decomposition perspective

In the past few years considerable attention has been given to the design of Multiple-Input Multiple-Output (MIMO) Eigenmode Transmission Systems (EMTS). This paper presents an in-depth analysis of a new MIMO eigenmode transmission strategy. The non-linear decomposition technique called Geometric Mean Decomposition (GMD) is employed for the formation of eigenmodes over MIMO flatfading channel. ...

Software contains bugs and bugs cost money. A good way to find some bugs quickly is the use of static code analysis. There are no exact numbers on the use of static code analyzers in the industry, but in our experience to few software developers actually make use of them. This thesis describes a survey that was conducted to find out why only so few developers in the Java community use static co...

. () Angenommen, es gibt a 6= b ∈ A mit g(f(a)) = g(f(b)). Da f injektiv ist, gilt f(a) 6= f(b). Dann muss aber auch g(f(a)) 6= g(f(b)) gelten, da g injektiv ist. () und () folgen analog. () Würde es f(a) = f(b) für a 6= b ∈ A gelten, so sollte auch g(f(a)) = g(f(b)) gelten, ein Widerspruch zu der Injektivität von g ◦ f . () und () folgen analog. Beispiel: Wir betrachten die Mengen A = ...

Let z = (z1, · · · , zn) and ∆ = ∑n i=1 ∂ 2 ∂z i the Laplace operator. A formal power series P (z) is said to be Hessian Nilpotent(HN) if its Hessian matrix HesP (z) = ( ∂ 2 P ∂zi∂zj ) is nilpotent. In recent developments in [BE1], [M] and [Z], the Jacobian conjecture has been reduced to the following so-called vanishing conjecture(VC) of HN polynomials: for any homogeneous HN polynomial P (z) ...
