Abstract: 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 realtime 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.

Key words: transport format blind detection, transport format combination indicator, CRC check
