  • PSK_encode_decode
    本源码通过声音传通数据,将数据调制二进制PSK(即BPSK)信号从喇叭发出来,另外一个接收程序接收到声音后,便可以解码出来,用到的技术有PSK编码、PSK解码、Windows录音,为了防止传输过程中出现的误,本原码采用rss纠错码,使得通讯更加稳定可靠。(The Source by voice through the data, binary modulation PSK (ie, BPSK) signals emitted the speaker, the other receiving program after receiving the sound, you can decode it, the techniques used have PSK encoding, PSK decoding, Windows Recording in order to prevent accidental transmission occurs, the primitive code using rss error correction code, making communications more reliable.)
