sound modulation in matlab
HI FRIENDS,
Can any body give the matlab code for Digital Modulation through Cable connecting sound cards between two PCs.
1.
For the voice communication system, which is also secure, the real time voice capture is done by microphone. As the programming tool is MATLAB, recording a sound involves opening the waveform audio hardware for input and passing buffers to the API to receive the sound data.
2.
For transmission we have implemented BPSK (Binary Phase Shift Keying) on an array of data in MATLAB.
WORK TO DO:
• Capture voice in matlab using its built in function.
• Implement that modulation scheme on that collected data
• Transmit the data in burst, that is lets say sending 200 samples and then give the delay of some time and then again send the samples and so on…
• On the receiver end, demodulate the data…
1.Voice capture through waverecord function of matlab------2. implement
BPSK and low pass filter code(which already Mentioned)------- 3. send data
through sound cards connecting PCs-----4.on receiver side implemnt the code of
BPSK in reverse order which will be demodulation--- 5. apply inverse low pass
filter(which is just the opposite of the code I sent u… )------6.play the voice
using Waveplay function of Matlab.
I need it as early as psiible, I'm really thankful for those who help me in this challenging project.
Best Regards..............
