well, once i get the binary representations, i can group the data and 
modulate it to a higher frequency and transmit it for example, if i am 
using BPSK modulation, i will then convert each zero into -1 and 
multiply it with the sin function with the sampling frequency with a 
hamming window. and so forth. yet, the first step is to have a 
successful representation of the data.
