Wi-Fi Scaling and Performance in Dense Frequency Planned Networks
Jonathan Ling, Howard Huang, Reinaldo Valenzuela
The capacity scaling of a Wi-Fi network with fixed transmit power is investigated. The 802.11 MAC appears to impose a hard limit on the area capacity by enforcing single transmissi…
Enhanced capacity & coverage by Wi-Fi LTE Integration
Jonathan Ling, Satish Kanugovi, Subramanian Vasudevan +1
Wi-Fi provides cost-effective data capacity at hotspots in conjunction with broadband cellular networks. The hotspots are required to capture a large number of users and provide hi…
Practical LTE and Wi-Fi Coexistence Techniques beyond LBT
Jonathan Ling, David Lopez-Perez, Mohammad R. Khawer
Coexistence with Wi-Fi is the key issue for unlicensed band LTE. The main coexistence mechanism is Listen-Before-Talk, whereby radio frequency energy is sensed over a short period…
Fast LDPC GPU Decoder for Cloud RAN
Jonathan Ling, Paul Cautereels
The GPU as a digital signal processing accelerator for cloud RAN is investigated. A new design for a 5G NR low density parity check code decoder running on a GPU is presented. The…
Compressed Sensing Algorithms for OFDM Channel Estimation
Jonathan Ling, Dmitry Chizhik, A. Tulino +1
Radio channels are typically sparse in the delay domain, and ideal for compressed sensing. A new compressed sensing algorithm called eX-OMP is developed that yields performance sim…
LWIP and Wi-Fi Boost Link Management
David Lopez-Perez, Jonathan Ling, Bong Ho Kim +3
3GPP LWIP Release 13 technology and its prestandard version Wi-Fi Boost have recently emerged as an efficient LTE and Wi-Fi integration at the IP layer, allowing uplink on LTE and…
