Performance of physical-layer network coded multi-way relay channels with binary signaling

The problem of full data exchange in multi-way relay channels (MWRCs) was considered in [1]. The algorithm proposed provides a throughput of 1/1.5N symbol per user per channel use (sym/U/CU) with binary signaling, which is a 33% increase compared to traditional relaying. In this paper, we analyze the average total energy consumption of the users for the proposed algorithm and compare it with traditional relaying. We also compare the power efficiency and error performance of this relaying scheme with other relaying techniques.
