A communication terminal based on frequency-hopping and spread spectrum TDMA system, For completing the design of RF module and link terminal, The software radio idea is used to realize the single channel transmit and multi-channel receiving of RF. The functions of digital module on baseband and protocol layer are realized by digital mode, through the design of the application software in the information terminal, providing the user with the means of underlying communication and test. The communication terminal provides good hardware and software support for the secondary development of the user application.
