Algorithm and Realization of the Key Modules for IQ-Separated Receiver Structure
Haoran Hao, Yukui Pei · 2018
The satellite communication systems continually increase the bandwidth to support high-throughput applications. However, the sampling rate of the analog-digital converter (ADC) limits the performance of the system. A dedicated receiver structure is proposed for IQ-separated sampling to support ultra-high sampling rate. This paper designs the key modules of the structure, including frequency error estimation, frame location and timing synchronization. The algorithm for the modules is descripted and the details of realization are focused. The simulation results demonstrate reasonable performance of the designed modules.
