The Research And Implementation Of Broadband Frequency Hopping Transceiver

As one of the basic techniques used in spread spectrum communication, frequencyhopping technology changes the carrier frequency rapidly, offering high resistant tointerference and secured data transmission in high speed.This paper focuses on the study and implementation of a broadband high-speedfrequency hopping radio transceiver, which uses GMSK modulation method and acombination of frequency hopping and time hopping techniques to spread spectrum. Beingat the forefront, transceiver plays a key role in wireless communication system.After introducing the basic principles of spread spectrum communication, this papergives the architecture of the communication system and the specific spread spectrummethod, as well as the modular design of the transceiver. The paper designed and simulatedthe key algorithm, and provides a software defined radio based solution for implementingthe transceiver. Finally, the implementation of the transceiver was fully tested.
