Random Access Algorithm of LTE TDD System Based on Frequency Domain Detection

摘要：

In this paper, the basic process of random access is briefly introduced first, a frequency-domain detection algorithms Suitable for criterion is proposed based on the structural characteristics of LTE TDD PRACH format4, PRACH signal launch model and key features of Zadoff-Chu sequence. Under the program in the detection of user testing, uplink synchronization estimate and analysis of the coverage area, the simulation results and conclusions are drawn finally. The simulation results show that the algorithm is low computational complexity, and can be carried out at the same time for multiuser detection and synchronization estimate compared to traditional time-domain matching method.
