Abstract :
In this paper, the design and implementation of a frequency hopping TDMA system is presented. The system is built around software defined radio concepts. The system architecture is described in detail, which is composed of three modules. High performance digital devices of DSP and FPGA realize the IF digitalization. Software implementation for frequency hopping synchronization is discussed and a method for direct sequence and frequency-hopping united acquisition is also introduced. Finally, TDMA network strategy is described. Applications in radio stations demonstrate that the frequency-hopping TDMA system is an advanced multiuser, voice and data communication system with good anti-interference ability.
