英国威格斯150GF30 PEEK详解：

In  this  paper,  we view  lossless compression as  a  limit  of lossy  compression with the distortion tending to zero.  More precisely, if we wish to reproduce Y1 losslessly,  we  will  set,  say,  Z1 =  Y1 with  d1 equal  to  Hamming  distance,  and then examine .  This convention and Definition 1 together yield a notion of lossless compression that is weaker than the one traditionally used. It is common instead to require that for all sufficiently large block lengths, there exists a code for which the probability of correctly reproducing the entire vector Y n  is arbitrarily close to 1.  But a weaker notion is desirable here since we are proving an outer bound or “converse” result.To  state  our  result,  let be  generic  random  variables  with  the distribution  of  the  source  at  a  single  time.  Let  Γo  denote  the  set  of  finite-alphabet random variables satisfying
