Cyclic Prefix Adaptation with Constant Overall Symbol Time for DFT-spread-OFDM and OFDM
Liangping Ma, Tao Deng, Alpaslan Demir
For DFT-spread-OFDM or OFDM, if the delay spread varies in a wide range and the symbol duration is relatively short, adapting the cyclic prefix (CP) duration rather than using a fi…
Four-Dimension Cross Constellations with Gray Mapping
Liangping Ma, Hae Chung, Byung K Yi
Recently a four-dimension (4D) cross constellation has been proposed, where a 4D-vector is drawn from two -ary QAM constellations, in an effort to reduce the peak-to…
QoE-based MAC Layer Optimization for Video Teleconferencing over WiFi
Tianyi Xu, Liangping Ma, Gregory Sternberg
In IEEE 802.11, the retry limit is set the same value for all packets. In this paper, we dynamically classify video teleconferencing packets based on the type of the video frame th…
On the Unicast Capacity of Stationary Multi-channel Multi-radio Wireless Networks: Separability and Multi-channel Routing
Liangping Ma
The first result is on the separability of the unicast capacity of stationary multi-channel multi-radio wireless networks, i.e., whether the capacity of such a network is equal to…
