Decoding errors

[ahsan1115]

Hello, I have integrated the LTE Receiver and I am using an lte signal file generated from OpenLTE project. The receiver is decoding the cell id correctly but it stucks at "received message vector". There is no information for MIB. I have attached the screenshots of the output and the receiver.Could anyone help me finding out where I am going wrong? The signal parameters are

1. Bandwidth = 5MHz
2. Cell id= 272

Hello, just in case anyone is around, I could run it and it shows like this:

Flowchart configured for BW=20MHz which means fftlen=1024 and N_rb_dl=50

and when executing:

In the meantime this is what I got. I need to examine the hole frames I suppose because I dont understand why that ofdm_lte_remove_cp_cvc_0 OUT of sync! message appears.

Cheers

@ahsan1115 hello, i was using the same method with you recently but i cannot get the correct cell_id. did your file come from ' LTE_file_recorder'?

@mingli001 Hi,bro.I was using 'LTE_fdd_dl_file_gen.py ' generate file, but i can not get the correct cell_id, did you fix the problem? By the way,is there anyone can get the correct cell_id with the file sampled by usrp x310/n210?

i am sorry to give you reply until now but i have give up it a few months ago.so i do not know how to fix it.

@mingli001 Thanks for your reply. I used the following flow graph and usrp n210( actually I saved the sampling file first ,than resampled the data up to 30.72MHz), after running several times I got the correct cell_id and MIB.
兄弟是中国的不?

是的呀
