Complementary Set Matrices Satisfying a Column Correlation Constraint
Di Wu, Predrag Spasojevic
Motivated by the problem of reducing the peak to average power ratio (PAPR) of transmitted signals, we consider a design of complementary set matrices whose column sequences satisf…

Incremental Redundancy Cooperative Coding for Wireless Networks: Cooperative Diversity, Coding, and Transmission Energy Gain
Ruoheng Liu, Predrag Spasojevic, Emina Soljanin
We study an incremental redundancy (IR) cooperative coding scheme for wireless networks. To exploit the spatial diversity benefit we propose a cluster-based collaborating strategy…
