Here's a screen shot of the output I get when I execute the 'lte_top_block_siso.grc' flowchart --

Traceback (most recent call last): File "/home/security/gr-lte/examples/lte_top_block_siso.py", line 201, in main() File "/home/security/gr-lte/examples/lte_top_block_siso.py", line 189, in main tb = top_block_cls() File "/home/security/gr-lte/examples/lte_top_block_siso.py", line 122, in init self.connect((self.lte_channel_estimator_0, 0), (self.lte_pbch_decoder_0, 0))

Please help!

Hi there

Is this the setup that you have for this "lte_top_block_siso.grc" flowchart? screenshot from 2017-04-17 03-44-34

Because from your output, this self.connect((self.lte_channel_estimator_0, 0), (self.lte_pbch_decoder_0, 0)) means that the out0 from Channel Estimator is connected to in0 of PBCH Decoder But from my image is not like that. It is more like the out0 from Channel Estimator should be connected to in1 of PBCH Decoder. Maybe this helps, I dont know.

Cheers Jarodcs

Check the resource blocks settings. Some of the blocks seem to use 6 resource blocks, while the PBCH Decoder uses 50. This change lets the flow graph run on my device.

Thanks. I got it figured out. The Mode of Generation was supposed to be Heir Block mode, not QT GUI.
