Using Parasitic Elements for Implementing the Rotating Antenna for MIMO Receivers
Abstract--We consider a new concept of a Multiple-InputMultiple-Output (MIMO) receiver which uses one active receiving antenna and multiple parasitic elements. The parasitic elemen...

Transmission Schemes for Multicarrier Broadcast and Unicast Hybrid Systems
Abstract--Wireless infrastructures can be conveniently categorized into two types: those that provide point-to-point `unicast' connectivity (e.g., cellular) and others that ar...

Redefinition of max-min fairness in multi-hop wireless networks
In this paper, it is shown that it is challenging to evaluate service fairness in multi-hop wireless networks due to intra-flow contention and unequal channel capacity. The convent...
