I already learned your sample code.
I have little problem here, is it possible to recover the symbol without demodulation?
Because I see your code, and there is no demodulation block
Could you expand on what you want out of the demodulation? There are several more examples in the NI Example finder under Toolkits and Modules>Modulation>Simulation. I have attached a screenshot of the MT FSK Mod-Demod.vi.
For example, under modulation toolkit pallete, I can find demodulation pallete,
There are demodulation PSK/FSK, etc
But, I didn't see it in you screenshot,,
Or, the demodulate FSK, in your screen shot can explained by several steps showed in your screenshot? (match filtering -> compute ideal symbol timing ->decimate -> map -> etc)
I noticed that the spreading code being used is 1 code..
What if I want to use several spreading codes?
For instance, I have a table contains 5 PN codes, that I used for spreading,,
How does the receiver de-spread it?
my problem is to setup syncronism in the system. I added sdr Tx and Rx to this model with configured triggering and made user-defined message, This message is properly decoded only cyclically. What measures can you advice to solve this problem with timing?
