Qian Wang, Feng Zhang, Jing Zhao, Zhe Li · 2020
In the receiving link of time and frequency hopping communication system, it is necessary to search multiple frequency points and time intervals according to a variety of time-frequency patterns at the same time, then complete blind data acquisition and effective information extraction. A large amount of data storage is required. This paper calculates and explains the data storage amount and storage speed of a certain time and frequency hopping communication system, compares and analyzes the advantages and disadvantages of the three storage methods and the applicable scenarios. Finally, the data storage method based on HBM2 in Stratix series FPGA is introduced in detail, and the practical application in the time and frequency hopping communication system verifies the storage speed and storage capacity of the method whether meets the system requirements.
