In this paper, we propose a distributed space-frequency transmit scheme in double selective channels for the OFDM cooperative system with two source and two destination nodes. In stead of interfering with each other, the two links cooperate by letting a source be a relay of the other one. Under this structure, the two sources can fulfill cooperative transmission together. We also design the frame...
In this paper, resource allocation for Orthogonal Frequency Division Multiple Access (OFDMA)-based Wireless Mesh Networks (WMNs) is investigated. First, the Even-Odd framework is modified to be better suited for different traffic patterns. Second, the scheduling problem in the modified Even-Odd framework is formulated as a Mixed Integer Quadratically Constrainted Programming (MIQCP), and a heuristic...
