PDSCH pseudorandom scrambling sequence
[seq,cinit] = ltePDSCHPRBS(enb,rnti,cwIndex,n)
[seq,cinit] = ltePDSCHPRBS(enb,rnti,cwIndex,n,mapping)

[
returns a column vector containing the first seq
,cinit
] = ltePDSCHPRBS(enb
,rnti
,cwIndex
,n
)n
outputs of
the Physical Downlink Shared Channel (PDSCH) scrambling sequence. It also
returns an initialization value cinit
for the pseudorandom
binary sequence (PRBS) generator. The function is initialized according to
cell-wide settings, enb
, 16-bit rnti
,
and cwIndex
, indicating which codeword this sequence
scrambles.
