Thank you for reply.I am trying to decode SIB in pdsch channel using USRP N210.The eNodeB details are:
Bandwidth:10 mhz
Sampling rate=15.36 MHZ
Num_tx_antenna=1,Num_rx_antenna=1 (SISO Mode)
DCI Format 1A
Resource allocation type=2
N_RB_DL=50
CFI=1
N_prb=2
MCS=6
TBS=176
I have decoded this using LTE_FDD_DL_SCAN Using USRP N210.
It looks MIB and PDCCH is decoded.
Info channel_found_begin freq=2140000000 dl_earfcn=300 freq_offset=2317.89185 phys_cell_id=6 sfn=495 n_ant=1 phich_dur=Normal phich_res=1 bandwidth=10
info channel_found_end freq=2140000000 dl_earfcn=300 freq_offset=2317.89185 phys_cell_id=6
In dlsch channel decode function in liblte_phy.cc line no:12397 while CRC checking the BER is upto 16 so that CRC fails and Not able to decode PDSCH Channel.
Is frequency offset value makes any difference.Because while decoding openlte eNodeB frequency offset is zero.
Suggest how to solve this problem.
