Diversity-Multiplexing Tradeoff for Frequency Fading Channels with CSIT

Abstract

In this contribution, we analyse the performance limits of a multiband frequency fading channels when perfect channel state information is available at the transmitter (CSIT). For various power allocation (RA) schemes such as water-filling, channel inversion and Haye's policy, we derive optimal constant-rate coding schemes that minimizes the information outage probability and show the potential gain of such techniques with respect to classical uniform power allocation
