v29_tx_state_t Struct Reference

#include <v29tx.h>

List of all members.

Public Attributes
int	bit_rate
	The bit rate of the modem. Valid values are 4800, 7200 and 9600.
get_bit_func_t	get_bit
	The callback function used to get the next bit to be transmitted.
void *	user_data
	A user specified opaque pointer passed to the callback function.
float	gain
complex_t	rrc_filter [2 *V29TX_FILTER_STEPS]
	The route raised cosine (RRC) pulse shaping filter buffer.
int	rrc_filter_step
	Current offset into the RRC pulse shaping filter buffer.
complex_t	current_point
	The current constellation position.
unsigned int	scramble_reg
	The register for the data scrambler.
uint8_t	training_scramble_reg
	The register for the training scrambler.
int	in_training
	TRUE if transmitting the training sequence, or shutting down transmission. FALSE if transmitting user data.
int	tep_step
int	training_step
	A counter used to track progress through sending the training sequence.
int	training_offset
	An offset value into the table of training parameters, used to match the training pattern to the bit rate.
uint32_t	carrier_phase
	The current phase of the carrier (i.e. the DDS parameter).
int32_t	carrier_phase_rate
	The update rate for the phase of the carrier (i.e. the DDS increment).
int	baud_phase
	The current fractional phase of the baud timing.
int	constellation_state
	The code number for the current position in the constellation.
get_bit_func_t	current_get_bit
	The get_bit function in use at any instant.
logging_state_t	logging
	Error and flow logging control.
