Zhiyong Bu · Journal of Jilin University · 2011
A Multi-Input Multi-Output (MIMO) based two-way Demodulate-and- Forward (DMF) relaying protocol was proposed. Incorporating MIMO technology into the relaying protocol can not only increase the spectral efficiency, but also enhance the transmission reliability. This relaying protocol was composed of two user terminals and one multi-antenna DMF relaying node. Moreover, to evaluate the performance of the proposed relaying protocol, closed-form Symbol Error Rate (SER) expressions of Quadrature Amplitude Modulation (QAM) for this MIMO-based DMF relaying protocol was derived. Simulation results demonstrate SER performance of the two-way DMF relaying system and verify the theoretical analysis.
