[Discuss-gnuradio] ofdm parameters

[Sara Chérif]

Hello ,

I want to implement ofdm system with these parameters:

FFT length=128

Occupied subcarriers=117.

4 pilots

1 DC

6 zeros subcarriers .

I put  these parameters in ofdm tx & ofdm Rx:

Occupied carriers =(range(-58,-42)+range(-41, -14) + range(-13, -7) + range(-6, 0) + range(1, 7) + range(7, 14) + range(15, 42)+range(43,60),)

pilots carriers=((-42, -14, 14, 42,),)

pilot symbols =(((-1,1j),(1,-1j),(-1,1j),(-1j,1),),)

But I got this error , I don't understand what is wrong

File "/usr/local/lib/python2.7/dist-packages/gnuradio/digital/digital_swig.py", line 4635, in make
    return _digital_swig.ofdm_equalizer_simpledfe_make(*args, **kwargs)
TypeError: in method 'ofdm_equalizer_simpledfe_make', argument 5 of type 'std::vector< std::vector< gr_complex,std::allocator< gr_complex > >,std::allocator< std::vector< gr_complex,std::allocator< gr_complex > > > > const &'

Thanks.
