An Interleaver-based Cooperation Diversity Protocol for Multiple-Relay Networks

A novel interleaver-based cooperation diversity protocol for wireless networks with multiple relays. In the proposed threshold-based decode-interleave-and-forward (TDIF) protocol, different relays are assigned with different interleavers, and the spatial diversity can be achieved through a symbol-by- symbol iterative detection method at the destination. Bit-error- rate performance analysis is also provided. Both analytical and numeric simulation results show that spatial diversity can be achieved in both synchronous and asynchronous wireless networks.
