Hi Team,
I am trying to make own cyclic prefix block in C++ in GNU Radio(removing
roll-off part and keeping all other parameters same). After connecting my
cyclic_prefix block to the already present FFT block in tx_ofdm.grc, i am
getting the following error:
Executing: /usr/bin/python2 -u

ValueError:* itemsize mismatch: fft_vcc_fftw0:0 using 512, CP_cc0:0 using 8*
*NOTE:* CP_cc is the block name that i gave when creating my own
cyclic_prefix block.
Can anyone help with your suggestions?
Thanks,
Simran Kaur
