Optimal Power Assignment for MIMO Channels Under Joint Total and Per-Group Power Constraints
Mahdi Khojastehnia, Ioannis Lambadaris, Ramy H Gohary +1
In this paper we consider a communication system with one transmitter and one receiver. The transmit antennas are partitioned into disjoint groups, and each group must satisfy an a…
Delay Optimal Scheduling for Chunked Random Linear Network Coding Broadcast
Emmanouil Skevakis, Ioannis Lambadaris, Hassan Halabian
We study the broadcast transmission of a single file to an arbitrary number of receivers using Random Linear Network Coding (RLNC) in a network with unreliable channels. Due to the…
Decoding and File Transfer Delay Balancing in Network Coding Broadcast
Emmanouil Skevakis, Ioannis Lambadaris
Network Coding is a packet encoding technique which has recently been shown to improve network performance (by reducing delays and increasing throughput) in broadcast and multicast…
Analysis and Design of Irregular Graphs for Node-Based Verification-Based Recovery Algorithms in Compressed Sensing
Yaser Eftekhari, Amir H. Banihashemi, Ioannis Lambadaris
In this paper, we present a probabilistic analysis of iterative node-based verification-based (NB-VB) recovery algorithms over irregular graphs in the context of compressed sensing…
On the Stability Region of Multi-Queue Multi-Server Queueing Systems with Stationary Channel Distribution
Hassan Halabian, Ioannis Lambadaris, Chung-Horng Lung
In this paper, we characterize the stability region of multi-queue multi-server (MQMS) queueing systems with stationary channel and packet arrival processes. Toward this, the neces…
Optimal Multi-Server Allocation to Parallel Queues With Independent Random Queue-Server Connectivity
Hussein Al-Zubaidy, Ioannis Lambadaris, Yannis Viniotis
We investigate an optimal scheduling problem in a discrete-time system of L parallel queues that are served by K identical, randomly connected servers. Each queue may be connected…
