Reliable of High Data Rate Using Spatial Multiplexing and Convolution Code [PDF]
Spatial Multiplexing (SM) can be achieved higher transmission rate without allocating higher bandwidth or increasing transmit power, so it is wildly used recently to serve the extremely demand of mobile communications.

Maximum Oriented Forcing Number for Complete Graphs
The \emph{maximum oriented $k$-forcing number} of a simple graph $G$, written $\MOF_k(G)$, is the maximum \emph{directed $k$-forcing number} among all orientations of $G$.

Zero forcing irredundant sets [PDF]
Irredundance has been studied in the context of dominating sets, via the concept of private neighbor. Here irredundance of zero forcing sets is introduced via the concept of a private fort and the upper and lower zero forcing irrdedundance numbers $\mbox{ZIR}(G)$ and $\mbox{zir}(G)$ are defined.

On the Relationships between Zero Forcing Numbers and Certain Graph Coverings
The zero forcing number and the positive zero forcing number of a graph are two graph parameters that arise from two types of graph colourings. The zero forcing number is an upper bound on the minimum number of induced paths in the graph that cover all ...

Bounds for the Zero Forcing Number of Graphs with Large Girth
The zero-forcing number, Z(G) is an upper bound for the maximum nullity of all symmetric matrices with a sparsity pattern described by the graph. A simple lower bound is δ ≤ Z(G) where δ is the minimum degree.

The Bipartite Zero Forcing Set for a Full Sign Pattern Matrix
For an m × n sign pattern P, we define a signed bipartite graph B ( U , V ) with one set of vertices U = { 1 , 2 , … , m } based on rows of P and the other set of vertices V = { 1 ′ , 2 ′ , … ,

On the zero forcing number of generalized Sierpinski graphs [PDF]
In this article we study the Zero forcing number of Generalized Sierpi\'{n}ski graphs $S(G,t)$. More precisely, we obtain a general lower bound on the Zero forcing number of $S(G,t)$ and we show that this bound is tight.

Automatic Modulation Classification for MIMO Systems via Deep Learning and Zero-Forcing Equalization
Automatic modulation classification (AMC) is one of the most critical technologies for non-cooperative communication systems. Recently, deep learning (DL) based AMC (DL-AMC) methods have attracted significant attention due to their preferable performance.

On the Design of Coherent Zero-Forcing Receiver for the Flat Fading MIMO Multiple-Access Channels [PDF]
Background and Objectives: Design of low-complexity receiver for space-time block coded (STBC) transmission over multiple-input multiple-output (MIMO) multiple-access channels has been subject of interest over the years.

A lower bound on the zero forcing number [PDF]
In this note, we study a dynamic vertex coloring for a graph $G$. In particular, one starts with a certain set of vertices black, and all other vertices white. Then, at each time step, a black vertex with exactly one white neighbor forces its white neighbor to become black.
