gnssBitSynchronize
Bit synchronizer for GNSS receivers
Description
[
performs bit synchronization on the input samplessyncidx
,numtr
] = gnssBitSynchronize(samples
,n
)samples
with a window size ofn
, as defined in[2]. The function searches the input samples for the maximum number of transitions from a positive to a negative value and from a negative to a positive value, and returns the bit synchronization indexsyncidx
and the number of transitions corresponding to each sample locationnumtr
.
全球导航卫星使用这个函数systems (GNSS) receivers that use code division multiple access (CDMA) schemes. These GNSS receivers include GPS, NavIC, and QZSS.
