The anti - jamming performance of the modem is greatly improved by time - frequency modulation according to the applying case 根據該調制解調器的應用場合,它采用時頻調制的方法使其抗干擾能力大大提高。
By experimentation , it is shown that time - frequency modulation is efficient and effective , which has rake and fault tolerant capacities in passband . the modem has strong ability of anti - jamming and error - correction which can finish the mission of communication under poor channel qualitative properties 經過實驗證明,時頻調制是一種簡捷有效方法,它具有很好的帶內分集接收效果和容錯能力,該調制解調器在信道質量很差的條件下,仍能完成數據通信的任務,具有很強的抗干擾和糾錯能力。
