Hi all, i want to generate white noise phisically to test my filters. i used the matlab commands (wgn(),sound()) to generate the noise using the sound card . But when i tested the fft of the output signal the spectrum is not flat which it should be. Is there any other way to generate the white noise using any software or hardware. Any response in this regard would be helpful. Thanks wa...

Greetings all, I am working on an experiment to demonstrate pulse shaping and bit error rate. The platform is DSK6711, using CCS2.2 and Matlab. The idea is simple: random bits are generated through a PN sequence generator, then they are "slowed down" by decimation (to 6kbps), a pulse-shaping filter is applied (sqrrcos) on what would be a transmitter, gaussian noise is added, then a matched...

Dear Sir, i want to implement bpsk demodulator in DSK6713. I have generated modulated signal from Matlab and providing this signal to DSK6713 board. The carrier signal frequency is 8khz and data is at 1KhZ rate. This means binary one and zero will have 8 cycles of carrier wave. I am taking the input from onboard codec and want to output demodulated signal on the same codec. ...
