Joint network coding and beamforming techniques for downlink channels
We propose a joint optimization of Network Coding and MIMO techniques to improve the downlink channel throughput of a wireless base station. Specifically, we consider a MIMO base...

Reliable Wireless Broadcasting with Near-Zero Feedback
We examine the problem of minimizing feedbacks in reliable wireless broadcasting, by pairing rateless coding with extreme value theory. Our key observation is that, in a broadcast ...

Golden Space-Time Block Coded Modulation
In a slow fading MIMO channel, we consider a coded modulation scheme where the inner code is the Golden Code. In this case, a lower bound for the minimum determinant is given by th...

Turbo equalization for block fading MIMO channels using random signal mapping
We present a novel turbo equalization scheme for block fading MIMO channels, where diversity is achieved using random signal mapping. We show that the computational complexity of ...
