Turbo Coded OFDM for Reducing PAPR and Error Rates
A selective-mapping (SLM) scheme which does not require the transmission of side information and can reduce the peak to average power ratio (PAPR) in turbo coded orthogonal frequen...

Lower Bounds on the Rate-Distortion Function of Individual LDGM Codes
Abstract-- We consider lossy compression of a binary symmetric source by means of a low-density generator-matrix code. We derive two lower bounds on the rate distortion function wh...

Unidirectional graph-based wavelet transforms for efficient data gathering in sensor networks
We design lifting-based wavelet transforms for any arbitrary communication graph in a wireless sensor network (WSN). Since transmitting raw data bits along the routing trees in WS...

Capacity of Channels With Action-Dependent States
We consider channels with action-dependent states: Given the message to be communicated, the transmitter chooses an action sequence that affects the formation of the channel state...

An Application-Driven MAC-layer Buffer Management with Active Dropping for Real-time Video Streaming in 802.16 Networks
— In this paper, we propose an application-driven MAC-layer buffer management framework based on a novel Active Dropping (AD) mechanism for real-time video streaming in IEEE 802....
