Abstract:

In this paper, we design distributed Turbo Product Codes (TPC) for cooperative communications. Specifically, to improve performance by using multiple relays, we propose Cyclic Interleaver (CI), a novel method for TPC to obtain independent Multiple Vertical Parities (MVP) for different relays. With this method, codewords in different relays are all in the same coding space of the product codes and hence can be jointly decoded. At the receiver, we further modify the existing turbo product decoder to iteratively decode the source information from data received from both the source node and the relay nodes. The system performance is demonstrated via simulations.

Keywords: Cooperative coding, cyclic interleaving, distributed turbo product codes, multiple relays.
