Software Arithmetic of Sending FFSK Signal in Portable Shunting Unit

平调手台设备中发送FFSK信号的软件算法

The results show that the FFSK has more virtues of phase continuation and higher band utilization than FSK and PSK/ DPSK.

结果表明：FFSK调制解调器具有相位连续、包络恒定的特征，频带利用率优于一般FSK和PSK/DPSK。

The software method is introduced by employing DDFS technology to realize the transformation of digital signal into FFSK signal. The conventional DDFS technology is improved a lot to achieve its function on single chip micro-computer without using too much resources.

采用直接数字频率合成（DDFS）技术，实现数字信号转换成FFSK信号的软件方法，对常用DDFS技术进行改进，使其能够在通用型单片机上实现而无需占用太多资源。
