MSK系统仿真利用simlink 其中加入了PCM编码解码(The MSK system simulation use simlink of which joined the PCM codec)

Base64编码说明 Base64编码要求把3个8位字节(3*8=24)转化为4个6位的字节(4*6=24),之后在6位的前面补两个0,形成8位一个字节的形式。 如果剩下的字符不...(Base64-encoded instructions require the Base64 encoding three 8-bit bytes (3* 8 = 24) was converted to 4 6 bytes (4* 6 = 24), then in front of the two s complement 6 0, 8 is formed bits in a byte form. If the rest of the characters do not ...)
