Experimental Demonstration of Nanosecond Accuracy Wireless Network Synchronization
Marcelo Segura, S. Niranjayan, Hossein Hashemi +1
Accurate wireless timing synchronization has been an extremely important topic in wireless sensor networks, required in applications ranging from distributed beam forming to precis…
Performance Metrics and Design Parameters for a Free-space Communication Link Based on Multiplexing of Multiple Orbital-Angular-Momentum Beams
Guodong Xie, Long Li, Yongxiong Ren +10
We study the design parameters for an orbital angular momentum (OAM) multiplexed free-space data link. Power loss, channel crosstalk and power penalty of the link are analyzed in t…
Achievable Rates of FDD Massive MIMO Systems with Spatial Channel Correlation
Zhiyuan Jiang, Andreas F. Molisch, Giuseppe Caire +1
It is well known that the performance of frequency-division-duplex (FDD) massive MIMO systems with i.i.d. channels is disappointing compared with that of time-division-duplex (TDD)…
Max-Weight Scheduling and Quality-Aware Streaming for Device-to-Device Video Delivery
Joongheon Kim, Andreas F. Molisch, Giuseppe Caire
We propose and analyze centralized and distributed algorithms for device-to-device video scheduling and streaming. The proposed algorithms address jointly the problems of device-to…
Caching Eliminates the Wireless Bottleneck in Video-Aware Wireless Networks
Andreas F. Molisch, Giuseppe Caire, David Ott +3
Cellular data traffic almost doubles every year, greatly straining network capacity. The main driver for this development is wireless video. Traditional methods for capacity increa…
Fundamental Limits of Caching in Wireless D2D Networks
Mingyue Ji, Giuseppe Caire, Andreas F. Molisch
We consider a wireless Device-to-Device (D2D) network where communication is restricted to be single-hop. Users make arbitrary requests from a finite library of files and have pre-…
