DESCRIPTION:Many interesting source and channel models have memory. When t
 he temporal dependence fades away sufficiently fast (or more precisely\, i
 f the source or noise process is ergodic)\, the standard coding techniques
  developed in classical Shannon theory can be extended beyond i.i.d. memor
 yless cases\, resulting in limiting expressions for rate--distortion and c
 apacity. The key idea behind this extension is the ergodic decomposition o
 f stationary processes\, which was utilized earlier by Gallager for rate--
 distortion theory of ergodic sources and by Kim for capacity of ergodic ch
 annels with or without capacity. Such interplay between information theory
  and ergodic theory is expected to play an important role in problems othe
 r than point-to-point source and channel coding. Some technical background
  can be found in  <br><br><br><br>
