Opportunistic Spectrum Access for Energy-Constrained Cognitive Radios
This paper considers a scenario in which a secondary user makes opportunistic use of a channel allocated to some primary network. The primary network operates in a time-slotted ma...

A Bio-Inspired Scheduling Scheme for Wireless Sensor Networks
— Sensor networks with a large amount of sensor nodes usually have high redundancy in sensing coverage. The network lifetime can be further extended by proper scheduling and putt...

High Rate Two-Way Amplify-and-Forward Half-Duplex Relaying with OSTBC
—In this paper, we derive tight upper and lower bounds for the average sum rate of two-way amplify-andforward (AF) half-duplex relaying, which show that two-way AF half-duplex re...

Precoder Designs for MIMO Broadcast Channels with Imperfect CSI
—In this paper, we propose two robust precoder designs for multiple-input multiple-output (MIMO) broadcast channels with imperfect channel state information (CSI). First, we cons...

Hardware scheduling support in SMP architectures
In this paper we propose a hardware real time operating system (HW-RTOS) that implements the OS layer in a dual-processor SMP architecture. Intertask communication is specified b...
