On the Achievability of Interference Alignment for Three-Cell Multi-User MIMO Cellular Networks
Interference channel interference alignment degrees of freedom Multi-User MIMO
2011/9/19
Abstract: An interference alignment (IA) based scheme is proposed by joint design of transmit precoding matrices and receive beamforming matrices for the three-cell Multi-User MIMO (MU-MIMO) cellular ...
NON-EXISTENCE OF SINGULAR CYCLES IN AQUADRIC DIFFERENTIAL SYSTEM WITH FINE FOCUS OF ORDER THREE
Homodinic heteroclinic centre-focus cr
2007/12/17
The problem of existence or non-existence of singular cycles (or komoclinic loops and keteroclinic cydes as being termed in the modern literature of nonlinear dyndric systems) is one of the most impor...
THE THRESHOLD OF SURVIVAL FOR PREDATOR-PREY VOLTERRA SYSTEM OF THREE SPECIES IN A POLLUTED ENVIRONMENT

2007/8/7
The effects of toxicants on two kinds of Volterra systems have been studied.One is a community consisting of two competitive predators and one prey; another,one predator and two competitive preys. The...
In this paper we consider the Predator-Prey model for three species in which the right-hand sides are periodic in time. A set of easily verifiable sufficient conditions is obtained for the existence o...
