MISO Broadcast Channel with Hybrid CSIT: Beyond Two Users
Sina Lashgari, Ravi Tandon, Salman Avestimehr
We study the impact of heterogeneity of channel-state-information available at the transmitters (CSIT) on the capacity of broadcast channels with a multiple-antenna transmitter and…
Blind MIMOME Wiretap Channel with Delayed CSIT
Sina Lashgari, Amir Salman Avestimehr
We study the Gaussian MIMOME wiretap channel where a transmitter wishes to communicate a confidential message to a legitimate receiver in the presence of eavesdroppers, while the e…
Linear Degrees of Freedom of the X-Channel with Delayed CSIT
Sina Lashgari, A. Salman Avestimehr, Changho Suh
We establish the degrees of freedom of the two-user X-channel with delayed channel knowledge at transmitters (i.e., delayed CSIT), assuming linear coding strategies at the transmit…
Timely Throughput of Heterogeneous Wireless Networks: Fundamental Limits and Algorithms
Sina Lashgari, A. Salman Avestimehr
The proliferation of different wireless access technologies, together with the growing number of multi-radio wireless devices suggest that the opportunistic utilization of multiple…
