Downlink performance and capacity of distributed antenna systems in a multicell environment
Wan Choi,Jeffrey G. Andrews +1 more
TL;DR: Analytically quantifies downlink capacity of multicell DAS for two different transmission strategies: selection diversity and blanket transmission, and shows that selection diversity is preferable to blanket transmission in terms of achievable ergodic capacity.

Journal ArticleDOI
Overcoming interference in spatial multiplexing MIMO cellular networks
TL;DR: It is argued that many of the traditional interference management techniques have limited usefulness when viewed in concert with MIMO, and emerging system-level interference-reducing strategies based on cooperation will be important for overcoming interference in future spatial multiplexing cellular systems.
Journal ArticleDOI
Multi-user diversity in a spectrum sharing system
TL;DR: The numerical and analytical results show that the multiuser diversity gain in a spectrum sharing system increases differently according to conditions given by the transmit power of secondary users, P, and a predetermined interference temperature, Q.
