DESCRIPTION:Random matrices for wireless communications : when Wigner meets
  Shannon\nMerouane Debbah\, Alcatel-Lucent Chair on Flexible Radio\, Supé
 lec\nThe asymptotic behaviour of the eigenvalues of large random matrices 
 has been extensively studied since the fifties. One of the first related r
 esult was the work of Eugène Wigner in 1955 who remarked that the eigenva
 lue distribution of a standard Gaussian hermitian matrix converges to a de
 terministic probability distribution called the semi-circular law when the
  dimensions of the matrix converge to infinity. Since that time\, the stud
 y of the eigenvalue distribution of random matrices has triggered numerous
  works\, in the theoretical physics as well as probability theory communit
 ies. However\, as far as communications systems are concerned\, until the 
 mid 90’s\, intensive simulations were thought to be the only technique t
 o get some insight on how communications behave with many parameters. All 
 this changed in 1997 when large system analysis based on random matrix the
 ory was discovered as an appropriate tool to gain intuitive insight into c
 ommunication systems. In particular\, the self-averaging effect of random 
 matrices was shown to be able to capture the parameters of interest of com
 munication schemes. Since the year 2000\, the results led to very active r
 esearch in many fields such as MIMO systems currently used in 4G technolog
 ies. This talk is intended to give a comprehensive overview of random matr
 ices and their application to the analysis and design of wireless communic
 ation systems (4G and 5G systems).
