Hey Nguyen Anh Duc, thanks for your input. It's nice to see that there seems to be some guys interested in the whole turbo EQ topic. These are some interesting points you mentioned. To be honest i never thought about using MLSE/MAP for the equalizer part. Same goes with another turbo decoder

2014-03-01 Thread Nasi
Helo all, I need your help for simulation of the Rayleigh fading. I know that I can use GNURADIO channel models, but I need to know how they simulated.  For example I am looking into the 'fading_model_impl.cc' in channel models of GNURADIO.  Can someone tell me how this is simulated? I heard

[Discuss-gnuradio] Clarification regarding Sample width in USRP.

2014-03-01 Thread Manu T S
Hello Everyone, From little bit of googling I understood that there are different sample width possible in USRP. If my understanding is correct, we can use 16/8 bit sample width. But my usrp block in GNU Radio lists complex float32 and complex int16, and VITA word 32 as the types. How can we

Marcus, Thanks.. Few more things. Is it correct to assume that In the wiretype, complex intx(x = 16 or 8) means that each I sample is represented by x bits, and Q sample is represented by x bits? What does the input type and output type in usrp sink and usrp source respectively, in GNU radio
