AlignTribs
[Rot,PattXReOut,PattXImOut,PattYReOut,PattYImOut,BoundValsOut,AlertsOut]
= AlignTribs(pSym,SigType,PattXReIn,PattXImIn,PattYReIn,PattYImIn,
BoundValsIn,AlertsIn)
pSym – single or dual polarization parameter vs. time:
.t0 – time of fi rst symbol
.dt – symbol duration
.Values – 1xN or 2xN array of complex values
SigType – integer value indicating signal modulation format
PattXReIn – data pattern of real part of X polarization
PattXImIn – data pattern of imag part of X polarization
PattYReIn – data pattern of real part of Y polarization
PattYImIn – data pattern of imag part of Y polarization
BoundValsIn – structure of boundary values from previous block
AlertsIn – structure of alerts accumulated before executing function
PattXReOut – data pattern of real part of X polarization, including
synchronization parameters
PattXImOut – data pattern of imag part of X polarization, including
synchronization parameters
PattYReOut – data pattern of real part of Y polarization, including
synchronization parameters
PattYImOut – data pattern of imag part of Y polarization, including
synchronization parameters
BoundValsOut – structure of boundary values to be passed to next block
AlertsOut – structure of alerts including any alerts raised during execution of
function
AlignTribs performs ambiguity resolution. The function acts on variable pSym
which is already corrected for phase and state of polarization, but for which
the tributaries have not been ordered. AlignTribs uses the data content of the
tributaries to distinguish between them.
