摘要：
The fundamental tradeoff between the transmission rate and the reliability of an one-side interference channel with relay is studied using the diversity-multiplexing tradeoff (DMT) as a measure. By analyzing the capacity and the outage probability, the DMT under strong interference condition is given. This paper concludes that the strength of the signal on interference channel will limit the maximum diversity and the strength of the signal forwarded by the relay will determine the diversity gain actually achieved. This paper also concludes that the power allocation ratio at the relay for the interference and the intended signal for one receiver does not affect the DMT.
