- 초록
- In this paper, we describe the NPRACH of 3GPP NB-IoT system and propose a possible receiver algorithm for NPRACH detection and timing advance estimation. We present simulation results for the performance of the random access preamble detection and timing advance for the proposed NPRACH detection scheme. In addition, we analyze the detection performance according to the detection threshold value and derive the optimal threshold value.
