Performance Analysis of MIMO Network Coding With SISO Physical-Layer Network Coding
In this paper, a two-step communication protocol combined with MIMO (Multiple Input Multiple Output) and network coding is proposed. A three nodes network with two transceiver antennas on relay node is taken. In transmitting phase ZF (Zero-Forcing) and MMSE (Minimum Mean SquarE) detecting techniques are used. In relay node forwarding network coding and Alamouti scheme are exploited together. Theoretical and simulative analyses prove that BER (Bit Error Rate) MMSE in transmitting phase is better than ZF and in relay forwarding MIMO alamouti outperforms the PNC (Physical-layer-Network Coding).
