Each character is transmitted in the form of a binary ASCII string (' 01100001 ' is the ASCII binary code for character ' a '). The first 4 bits of the first character were modulated as a 16 QAM symbol and loaded on the second most negative frequency. The first 4 bits of the second character were modulated as a 16 QAM symbol and loaded on the third most negative frequency. Similarly, the last 4 bits of the last character were modulated as a 16QAM symbol and loaded on the positive most frequency. The other characters are similarly loaded on frequencies in between.
