Abstract: Efficient ranging technique is utilized to achieve the uplink time slot synchronization and power control in WiMAX/IEEE802.16e network．The principle of ranging which is involved in the generation,transmission and detection of ranging codes is analyzed firstly．Then,the key techniques of uplink ranging processing which includes the power detection and time delay estimation is investigated．Finally,the DSP implementation of ranging processing is given in detail,the test results show that the proposed ranging scheme is feasible.

Key words: Ranging,Differentially multiplying,Power detection,Time delay estimation
