Network coded multipath and related techniques

Emre Telatar, Arno Schneuwly, Derya Malak

Techniques are disclosed for adaptive coding and scheduling of packets in wireless networks. The adaptive coding and scheduling can be achieved by utilizing a discrete water filling (DWF) scheme. In an example, a computer-implemented method to adaptively c ...
