摘　　要： 提出并分析了UTRAN侧基于CRC校验的传输格式方案,确定了路径选择门限D.该方案在不牺牲接收性能的前提下避免了Rake按所有可能的扩频因子进行多次的解调,降低了对资源的需求,尤其是对Rake的实时性要求.理论分析和仿真结果表明,该方案具有良好的性能,并且硬件复杂度低,处理时延小,易于实现. We present and analyse transport format blind detection scheme using CRC check on UTAN side. The path selection threshold D is determined based on software simulation. The scheme enables Rake receiver to avoid demodulations as many as the possible spread factors without receiving performance degradation. The scheme requires less resource especially the Rake realtime requirement. From the theoretical analysis and simulation results presented here it can be drawn that the new method can provide good performance with less cost of hardware complexity and process time delay.
