Hi,
I have been working on LTE UPLINK in GNURADIO with help of OFDM grc file and facing a problem in generation of it. Changing in tx_ofdm grc file which is already present in gnuradio, I am using one sync_word for SRS generation and keeping the second sync_word as blank ( or all 0 ) then the error is coming on carrier allocator block like this
self.digital_ofdm_carrier_allocator_cvc_0 = digital.ofdm_carrier_allocator_cvc(fft_len, occupied_carriers, pilot_carriers, pilot_symbols, (sync_word1), length_tag_key)
File "/usr/lib/python2.7/dist-packages/gnuradio/digital/digital_swig.py", line 5788, in make
return _digital_swig.ofdm_carrier_allocator_cvc_make(*args, **kwargs)
TypeError: in method 'ofdm_carrier_allocator_cvc_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 &'
As I am using SRS sync_word value as shown below for 64fft length
[0.7071 - 0.7071j, -0.7071 + 0.7071j, 0.7071 + 0.7071j, -0.7071 - 0.7071j, -0.7071 + 0.7071j, 0.7071 - 0.7071j, 0.7071 + 0.7071j, -0.7071 + 0.7071j, -0.7071 - 0.7071j, -0.7071 + 0.7071j, 0.7071 + 0.7071j, -0.7071 + 0.7071j, -0.7071 - 0.7071j, -0.7071 + 0.7071j, 0.7071 + 0.7071j, 0.7071 + 0.7071j, 0.7071 - 0.7071j, 0.7071 + 0.7071j, -0.7071 + 0.7071j, -0.7071 - 0.7071j, -0.7071 + 0.7071j, -0.7071 - 0.7071j, 0.7071 - 0.7071j, -0.7071 - 0.7071j, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ]
Please correct me or suggest some other way to generate LTE signal in GNURADIO
THANKING YOU !!!!
