----------
|
|
|
|
|
|
This directory contains the transport channel coding/decoding functions for both OpenAirInterface and a subset of LTE/WiMAX/WIFI MODEMS.
|
|
They can only be compiled on x86 platforms (at least sse,sse2 are required).
|

Use of unitary tests
|
|
--------------------
|
|
|
|
Three tests can be compiled with "make". They are standalone and do not require the rest of openair1.
|
|
They only test the following files:
|
|
|
|
crc_byte.c
|
|
ccoding_byte.c
|
|
ccdoing_byte_lte.c
|
|
3gpp_turbo_decoder_sse.c
|
|
3gpplte.c
|
|
viterbi.c
|
|
viterbi_lte.c
|
|
|
|
After "make", you should have three executables, turbo_test, rate13cc_test and rate12cc_test which should
|
|
all have executed and printed proof of correct execution (at least for the default block lengths). Further
|
|
tests should be performed with the performance tests in TESTBENCH, which require the rest of openair1.
