Collaboration diagram for Synchronization:

Classes
class	gr_clock_recovery_mm_cc
	Mueller and Müller (M&M) based clock recovery block with complex input, complex output.This implements the Mueller and Müller (M&M) discrete-time error-tracking synchronizer. The complex version here is based on: Modified Mueller and Muller clock recovery circuit Based: G. R. Danesfahani, T.G. Jeans, "Optimisation of modified Mueller and Muller algorithm," Electronics Letters, Vol. 31, no. 13, 22 June 1995, pp. 1032 - 1033. More...
class	gr_clock_recovery_mm_ff
	Mueller and Müller (M&M) based clock recovery block with float input, float output.This implements the Mueller and Müller (M&M) discrete-time error-tracking synchronizer. More...
class	gr_correlate_access_code_bb
	Examine input for specified access code, one bit at a time.input: stream of bits, 1 bit per input byte (data in LSB) output: stream of bits, 2 bits per output byte (data in LSB, flag in next higher bit) More...
class	gr_costas_loop_cc
	Carrier tracking PLL for QPSKinput: complex; output: complex The Costas loop can have two output streams: stream 1 is the baseband I and Q; stream 2 is the normalized frequency of the loop. More...
class	gr_mpsk_receiver_cc
	This block takes care of receiving M-PSK modulated signals through phase, frequency, and symbol synchronization.This block takes care of receiving M-PSK modulated signals through phase, frequency, and symbol synchronization. It performs carrier frequency and phase locking as well as symbol timing recovery. It works with (D)BPSK, (D)QPSK, and (D)8PSK as tested currently. It should also work for OQPSK and PI/4 DQPSK.

class	gr_ofdm_insert_preamble
	insert "pre-modulated" preamble symbols before each payload. More...
class	gr_pll_carriertracking_cc
	Implements a PLL which locks to the input frequency and outputs the input signal mixed with that carrier.input: stream of complex; output: stream of complex. More...
class	gr_pll_freqdet_cf
	Implements a PLL which locks to the input frequency and outputs an estimate of that frequency. Useful for FM Demod.input: stream of complex; output: stream of floats. More...
class	gr_pll_refout_cc
	Implements a PLL which locks to the input frequency and outputs a carrierinput: stream of complex; output: stream of complex. More...
class	gr_pn_correlator_cc
	PN code sequential search correlator. More...
class	gr_simple_correlator
	inverse of gr_simple_framer (more or less) More...
class	gr_simple_framer
