Research on Repeater Technology Based on Software Defined Radio

In recent years, the field of communication technology has developed vigorously, the requirements for signal transmission quality have also gradually increased, covering a wide range, and high-quality transmission signals can better meet people’s daily lives and applications. Aiming at the problem that communication transmission is limited by distance in real life, weakening the quality of transmission signals, the repeater is implemented in the GNU Radio programming environment using a general software radio platform, at the same time, the relevant parameters of the repeater can be dynamically configured, the repeater signal can be observed in real time, which has high scalability. The actual test results show that the designed repeater realizes the forwarding of voice signals, increases the distance range of signal transmission of handheld stations, and improves the stability of data transmission, the repeater has certain application prospects in voice data communication, and provides a new idea for the design of the repeater.
