Hybrid Coding for Gaussian Broadcast Channels with Gaussian Sources
Rajiv Soundararajan, Sriram Vishwanath
This paper considers a degraded Gaussian broadcast channel over which Gaussian sources are to be communicated. When the sources are independent, this paper shows that hybrid coding…

Adaptive Sum Power Iterative Waterfilling for MIMO Cognitive Radio Channels
Rajiv Soundararajan, Sriram Vishwanath
In this paper, the sum capacity of the Gaussian Multiple Input Multiple Output (MIMO) Cognitive Radio Channel (MCC) is expressed as a convex problem with finite number of linear co…
