摘　　要：介绍了一种包括ISI和ICI的性能分析方法。并用该方法对组播广播单频网因载频同步和时间同步误差引起的性能下降进行了分析。If the UE in a MBSFN receives signals which are exposed to different carrier offsets and doppler spread, it will lead to inter-channel interference （ICI）, resulting into performance degradation. A method to analyze the performance including IS1 and IC1 is presented in this paper. Furthermore, frequency offset and time synchronization errors are also investigated.
