carrier_rec_init
Initialization of a carrier recovery loop object
Calling sequence
cr = carrier_rec_init(ped[, lf])
cr = carrier_rec_init(ped[, lf])
Parameters
- ped:
phase error detector object
- lf:
loop filter object (if not specified, the default is a first order loop, with time constant of 10 samples)
phase error detector object
loop filter object (if not specified, the default is a first order loop, with time constant of 10 samples)
Description
Initialize a carrier recovery loop, using a given Phase Error Detector (ped) and Loop Filter (lf). For example, so a to recover the carrier of a BPSK signal, one can use ped_init as a phase error detector, and lf_init (first or second order loop) as a loop filter.
