Distributed space time frequency coding (DSTFC) schemes address problems of performance degradation encountered by cooperative broadband networks operating in highly mobile environments. Channel state information (CSI) acquisition is, however, imprac

For a multiuser multiple-input-multiple-output (MIMO) overlay cognitive radio (CR) network, a spacetime opportunistic interference alignment (ST-OIA) technique has been proposed that allows spectrum sharing between primary users (PU) and secondary us

Cooperative Spectrum Sensing has been investigated in Rayleigh-fading environments over non-ideal reporting channels, where the simulation results have shown that its performance is limited by the probability of reporting errors. This paper proposes

In this paper, a source-assisting differential distributed space time block coding (SA-DDSTBC) scheme is proposed for cooperative networks. Firstly, in most existing works on distributed space time block coding (DSTBC), the destination node is assume
