initially by using ADC module of a 16F877A , PIC samples speaker's output of my computer at the rate of 128Kbps
Good luck getting a PIC16F877A, or any PIC to sample ANYTHING at 128kbps

and then some coding techniques will be executed on ADC results.
What 'techniques would those be?

then by using a digital modulator module, i will send the signals and then in the receiver side, i will demodulate this signals by using a digital demodulator module.
There's a lot of those out there. Why not use the ones you used in the above linked post?
