Detailed Description

Decodes a VITA 49 or I/Q data packet.

The Vita49Packet class is used to decode VITA 49 or raw I/Q data coming from an NDR-class radio.

This class is designed to be as flexible as possible in dealing with data streams, since each NDR-class radio varies in how it packages data streams.

Constructor & Destructor Documentation

Vita49Packet() [1/2]

Vita49Packet	(	int	vitaType,
		size_t	payloadSize,
		size_t	vitaHeaderSize,
		size_t	vitaTailSize,
		bool	byteSwapped,
		bool	iqSwapped,
		unsigned char *	rawData = NULL,
		size_t	rawDataLen = 0
	)

Constructs a Vita49Packet object.

Parameters

vitaType	The VITA 49 enable option value. The range of valid values depends on the radio, but 0 always disables VITA 49 formatting. In that case, the data format is raw I/Q.
payloadSize	The VITA 49 or I/Q payload size for the radio, in bytes. If VITA 49 output is disabled, then this parameter provides the total size of all raw I/Q data transmitted in a single packet.
vitaHeaderSize	The VITA 49 header size for the radio, in bytes. If VITA 49 output is disabled, then this parameter is ignored.
vitaTailSize	The VITA 49 tail size for the radio, in bytes. If VITA 49 output is disabled, then this parameter is ignored.
byteSwapped	Whether the bytes in the packet are byte-swapped with respect to the endianness employed by the host operating system.
iqSwapped	Whether I and Q data in the payload are swapped.
rawData	A pointer to the buffer of raw data received from the radio.
rawDataLen	The length of the raw data buffer.

Member Function Documentation

dump()

std::string dump

(

)

Gets a string dump of the contents of the data packet.

Returns

A string describing the contents of the packet.

Definition at line 417 of file Vita49Packet.cpp.

getSampleI()

int16_t getSampleI

(

int

sample

)

Gets the I component of a given data sample.

Parameters

sample

The sample number (0-based).

Returns

The I component of the sample. This method will return 0 if the sample number is out of bounds.

Definition at line 378 of file Vita49Packet.cpp.

getSampleQ()

int16_t getSampleQ

(

int

sample

)

Gets the Q component of a given data sample.

Parameters

sample

The sample number (0-based).

Returns

The Q component of the sample. This method will return 0 if the sample number is out of bounds.

Definition at line 386 of file Vita49Packet.cpp.

isVita49()

bool isVita49

(

)

const

Indicates whether the packet data is in VITA 49 format.

Returns

True if the data is VITA 49, False otherwise.

Definition at line 368 of file Vita49Packet.cpp.

operator=()

Vita49Packet & operator= ( const Vita49Packet &  src )

virtual

Assignment operator.

Parameters

src	The object to assign properties from.

Definition at line 327 of file Vita49Packet.cpp.

rawDataHex()

std::string rawDataHex ( )

inline

Gets the raw data in hex-string format.

Returns

A hex string representing the raw data.
