Re: [Discuss-gnuradio] RFID at 2.4GHz simulation-Encoding, Modulation techniques (grc implementation)

[stefosee]

Hello again,
I've already implemented the modulation schemes i'm writing above, plus the
manchester encoder.
No i'm trying to design the biphase space (fm0) encoder.
For the manchester i used 2 square sources, one for the data and another one
for the clock with the double frequency and i use an XOR between them. 

So, for a clock: 
10 10 10 10 10 10      and data 101110:
11 00 11 11 11 00      i have an output like that:
01 10 01 01 01 10      which is the expected one.

Assuming that it works right, now, i'm trying to design the fm0. 
I know its harder because each output is related to the previous one. 
Is there any fm0 already implemented? Or is there any link to help me do it?

TIA
