We would also select a Discussion Leader. Through the m onth\, each of the participants would read the article. At the next meetin g\, the Discussion Leader would lead a discussion of that article\, starti ng with his/her own appraisal. In this way\, it is hoped that we could all broaden our understanding of the field and further develop a sense of com munity. 1st rule of 1st Tuesday Journal-Paper Club: tell everyone about 1s t Tuesday Journal-Paper Club.\n\nSpeaker(s): \, \, \, \n\nAgenda: \nAbstra ct\n\nFor the fully connected K user wireless interference channel where t he channel coefficients are time-varying and are drawn from a continuous d istribution\, the sum capacity is characterized as C(SNR)=K/2log(SNR)+o(lo g(SNR)) . Thus\, the K user time-varying interference channel almost surel y has K/2 degrees of freedom. Achievability is based on the idea of interf erence alignment. Examples are also provided of fully connected K user int erference channels with constant (not time-varying) coefficients where the capacity is exactly achieved by interference alignment at all SNR values. \n\nBldg: Brewhouse Brisbane\, 601 Stanley St.\, Woolloongabba\, Queenslan d\, Australia\, 4102 LOCATION:Bldg: Brewhouse Brisbane\, 601 Stanley St.\, Woolloongabba\, Queen sland\, Australia\, 4102 ORGANIZER:a.bradley@itee.uq.edu.au SEQUENCE:2 SUMMARY:1st Tuesday Journal-Paper Club: November 2015 meeting URL;VALUE=URI:https://events.vtools.ieee.org/m/35858 X-ALT-DESC:Description: <br /><p>Provisonally for our first Tuesday in Nove mber Vaughan Clarkson has kindly agreed to be our reader leader on Interfe rence Alignment.
