A turbo-like symbol by symbol decoder for randomly distributed space-time coding in amplify-and-forward relay networks

In this letter, a simple distributed space-time coding scheme is introduced by allocating random interleavers to each relay node in amplify-and-forward (AF) network. By using multiuser definition each rely node provides an interference to the detected signal, a turbo-like symbol by symbol decoder is also introduced. The complexity involved grows only linearly with the number of relay nodes. Simulation results show an acceptable improvement to previous works in the high SNR region.
