摘要

在这篇文章中，我们分析了当发射机(CSIT)有完美的信道状态信息时，多频带频率衰落信道的性能限制。对于各种功率分配(RA)方案，如充水、信道反转和Haye策略，我们推导了最优的恒率编码方案，使信息中断概率最小化，并显示了这些技术相对于经典的均匀功率分配的潜在增益

Diversity-Multiplexing Tradeoff for Frequency Fading Channels with CSIT

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
