Abstract： In LTE system, physical random access channel (PRACH) is the first step to establish a stable connection and normal conversation between user terminals and the network，it is also the key to get the uplink synchronization. Based on the principal analysis of the TDD-LTE physical random access channel transmitter ,this paper put forward a algorithm of the receiver for the LTE random access channel，and establish the link code for the performance simulation，and the result meet to the LTE physical layer protocols of performance requirements.
