2. minor modifications in dlsch_demodulation.c for 2 eNB TX antennas, 1 RX antenna. Inconsistant indexing of some arrays in this case.
3. change in config_load_configmodule.c : removed exit(-1) when no configuration file is used. This makes unitary simulators exit. Effect on lte-XXsoftmodem TBC.
receiver. THe proposed solution is to replace the average channel level with
median = (max+min)>>1.
For these reasons lsch_channel_level_median is introduced.
1. It's no need to modify LTE-RRC's ASN.1 file for enabling option group
feature in generate_asn1.
2. It's no need to patch the C header files generated from
LTE-RRC/S1AP/X2AP's ASN.1 in fix_asn1.
3. It's no need to pre-process S1AP/X2AP's ASN.1 for enabling information
object class feature by asn1tostruct.py.
This commit requires an un-official version of asn1c which are
collaboration of asn1c community members and `build_helper` is modified
in this commit accordingly :
https://github.com/brchiu/asn1c/tree/velichkov_s1ap_plus_option_group
This asn1c can also convert ASN.1 of 5G NR RRC (38.331, v15.1.0) and
generate C files with -findirect-choice command line option without
tweaking ASN.1 file.
Examples for how to use this asn1c for S1AP are in S1AP files, e.g.
s1ap_eNB_nas_procedures.c and s1ap_eNB_handler.c.
There is an modified openair-cn (based on tag 0.5.0) with this new asn1c at :
https://github.com/brchiu/openair-cn/tree/new-asn1c
Basic S1AP interaction and data transfer operation between OAI eNB and
this modified openair-cn has been tested.
Note: Community version of asn1c is keeping evolved to provide better usage.
2. Remove get_pmi from PHY_SRC_UE and add it instead to PHY_SRC_COMMON.
3. Linking lte-uesoftmodem and lte-uesoftmodem-nos1 targets with ${ATLAS_LIBRARIES}.
1. Moving get_pmi into a separate file and making corresponding
changes in CMakeLists.txt.
2. Creating PHY_MEX library with functions required for the receiver
mex-functions.
3. Making necessary changes in defs_UE.h so that mex-functions
do not complain about multiple LOG_ calls.
to linear_preprocessing_rec.c.
2. Adding linear_preprocessing_rec.c to PHY_SRC_UE library.
3. Adding mmse_flag and mmse functionalities to dlsch_demodulation.
4. For now, dlsim_tm4 will not compile.
as more transparent functions independent from the number of
resource elements in RB. They will tream as many resource
elements as there is in the vector that is passed.
