为了研究干扰中继信道中继节点对信道容量性质及实际传输的影响,研究了单边干扰中继信道在取得复用增益的同时获得分集增益的能力.通过建立具有信息感知中继的单边干扰中继信道的模型,对信道容量和中断概率进行分析,得到了相应的表达式,计算得到了高信噪比下分集增益与复用增益的折中关系.将干扰中继信道下的分集增益与复用增益折中的数值仿真结果与无中继节点Z形信道下的结果进行对比,结果表明,采用中继节点转发能在保证复用增益的同时提高分集增益.
In order to study the influence of relay nodes on the capacity and actual transmission of relay channel, we study the capability of unilateral interference relay channel to obtain diversity gain while gaining multiplexing gain.By establishing a single side with information-aware relay Interference relay channel model, the channel capacity and interrupt probability analysis, obtained the corresponding expression, calculated the high signal to noise ratio under the diversity gain and multiplexing gain compromise will interfere with the channel under the diversity The simulation results of the gain and the multiplexing gain are compared with the results of the Z-channel without the relay node. The results show that the repeater gain can be improved while the diversity gain is guaranteed.
