Energy Efficient Scheduling
Energy Efficient Scheduling
Abstract — This paper focuses on energy-efficient packet transmission with individual packet delay constraints. The optimal offline scheduler (vis-a-vis total transmission energy), assuming information of all packet arrivals before scheduling, was developed by Zafer, et al. (2005) and Chen et al. (2006).

Performance of 802.11b/g in the Interference Limited Regime
Performance of 802.11b/g in the Interference Limited Regime
Abstract — Signal to interference plus noise ratio, SINR, is one of the main factors that affects the quality of wireless communication. While the impact of white Gaussian noise on a wireless channel is well understood, impact of interference remains one of the less explored areas.

Construction of Irregular LDPC Codes by Quasi-Cyclic Extension
Construction of Irregular LDPC Codes by Quasi-Cyclic Extension
Abstract—In this correspondence, we propose an approach to construct irregular low-density parity-check (LDPC) codes based on quasi-cyclic extension. When decoded iteratively, the constructed irregular LDPC codes exhibit a relatively low error floor in the high signal-to-noise ratio (SNR) region and are subject to relatively few undetected errors.
