Joint-over-Transmissions Project and Forward Relaying for Single Carrier Broadband MIMO ARQ Systems
Hatim Chergui, Tarik Ait-Idir, Mustapha Benjillali, Samir Saoudi · 2011
In this contribution, we present a new class of project-and-forward (PF) relays operating with broadband MIMO hybrid ARQ-aided cooperative systems. Their architecture enables to jointly perform the orthogonal projection over multiple ARQ transmissions, increasing thereby the relay diversity order and achieving an interesting power gain over amplify-and-forward (AF)-based relaying schemes.
