Competitive Ratio Analysis of Online Algorithms to Minimize Data Transmission Time in Energy Harvesting Communication System
Rahul Vaze
We consider the optimal online packet scheduling problem in a single-user energy harvesting wireless communication system, where energy is harvested from natural renewable sources,…
Percolation on the Signal to Interference Ratio Graph with Fading
Rahul Vaze
A wireless communication network is considered where any two nodes are connected if the signal-to-interference ratio (SIR) between them is greater than a threshold. We consider the…
Sub-modularity and Antenna Selection in MIMO systems
Rahul Vaze, Harish Ganapathy
In this paper, we show that the optimal receive antenna subset selection problem for maximizing the mutual information in a point-to-point MIMO system is sub-modular. Consequently,…
How Many Transmit Antennas to Use in a MIMO Interference Channel
Rahul Vaze
The problem of finding the optimal number of data streams to transmit in a multi-user MIMO scenario, where both the transmitters and receivers are equipped with multiple antennas i…
Percolation and Connectivity on the Signal to Interference Ratio Graph
Rahul Vaze
A wireless communication network is considered where any two nodes are connected if the signal-to-interference ratio (SIR) between them is greater than a threshold. Assuming that t…
Super Critical and Sub Critical Regimes of Percolation with Secure Communication
Rahul Vaze
Percolation in an information-theoretically secure graph is considered where both the legitimate and the eavesdropper nodes are distributed as Poisson point processes. For both the…
Competitive Use of Multiple Antennas
Rahul Vaze
A game theoretic framework is presented to analyze the problem of finding the optimal number of data streams to transmit in a multi-user MIMO scenario, where both the transmitters…
