Radio Resource Allocation for Scalable Video Services over Wireless Cellular Networks
Mostafa Zaman Chowdhury, Tuan Nguyen, Young-Il Kim +2
Good quality video services always require higher bandwidth. Hence, to provide the video services e.g., multicast/broadcast services (MBS) and unicast services along with the exist…
Quantum messages with signatures forgeable in arbitrated quantum signature schemes
Taewan Kim, Jeong Woon Choi, Nam-Su Jho +1
Even though a method to perfectly sign quantum messages has not been known, the arbitrated quantum signature scheme has been considered as one of good candidates. However, its forg…
Load Balancing in Two-Tier Cellular Networks with Open and Hybrid Access Femtocells
Dongmyoung Kim, Taejun Park, Hyoil Kim +1
Femtocell base station (BS) is a low-power, low-price BS based on cellular communication technology. It is expected to become a cost-effective solution for improving the communicat…
Fundamental Limits in Correlated Fading MIMO Broadcast Channels: Benefits of Transmit Correlation Diversity
Junyoung Nam
We investigate asymptotic capacity limits of the Gaussian MIMO broadcast channel (BC) with spatially correlated fading to understand when and how much transmit correlation helps th…
