hi！
i'm testing bcp_testproject in PDK 6670 about test_lte_ul to decode PUSCH.
i modify the bcp config,delete the RD Submodule to look the result of ssl.
ssl config is
if (radioStd == Bcp_RadioStd_LTE)
{
pSslHdrCfg->modeSelCfg.split_mode_en = numLayers-1;
pSslHdrCfg->modeSelCfg.jack_bit = 0;
pSslHdrCfg->modeSelCfg.lte_descrambler_en = 1;
pSslHdrCfg->modeSelCfg.mod_type_sel = (Bcp_ModulationType) (mod/2);
pSslHdrCfg->modeSelCfg.cmux_ln = (Bcp_CmuxLength) (numOFDMSymPerSubfrm - 9);
pSslHdrCfg->modeSelCfg.q_format = (Bcp_QFormat) (Qfmt);
Rprime1 = 12 * prbList[Rprime] * numLayers;
pSslHdrCfg->modeSelCfg.b_matrix_sel = gind_row_index(Rprime1 * mod);
pSslHdrCfg->modeSelCfg.rmux_ln_index = Rprime;
pSslHdrCfg->ri_ln = 0;//numRi;-------modified
pSslHdrCfg->ack_ln = 0;//numAck;------modified
pSslHdrCfg->cinit_p2 = cinit;
}
the result is 288 bytes .(descramble_LLR=)
and then ,i disable the descrambler
pSslHdrCfg->modeSelCfg.lte_descrambler_en = 0;
the result is (undescramble_LLR=)
I use matlab generate the scramble code according to lte 36.211 is (cinit=115948)
how the ssl descramble the LLR?
descramble_LLR=(1-2*scramble_code)*undescramble_LLR.
is it correct?
expect for your answers
