Hello.
Thank you so much for your attention.
I'm writing my own block using python, trying to get the output of the *OFDM
Channel Estimation* block to be the input of my own block.
I'm getting the following error:
*RuntimeError: itemsize mismatch: ofdm_chanest_vcvc0:0 using 512,
cir_sink_c0:0 using 8*
I'm using:
*def __init__(self, fft_len): gr.sync_block.__init__(self,
name="cir_sink_c", in_sig=[np.complex64],
out_sig=None) self.fft_len = fft_len*
and in the YML file:
*inputs:- label: in domain: stream dtype: complex vlen: ${fft_len}*
I've tried to use *complex_vetor *in the dtype, but I kept getting
this error message:
* File
"/root/prefix/lib/python3/dist-packages/gnuradio/grc/core/ports/port.py",
line 91, in item_size return Constants.TYPE_TO_SIZEOF[self.dtype] *
self.vlenKeyError: 'complex_vector'*
I've also tried to use *np.complex128 *in the in_sig, but that doesn't work
either.
Does anyone a solution for this?
Thank you so much for your help!
Yours sincerely,
Vinicius.
