Detailed Description

ARGOS Low Data Rate HDLC decoder.

Member Typedef Documentation

sptr

using gr::satnogs::argos_ldr_decoder::sptr = std::shared_ptr<argos_ldr_decoder>

The decoder take as input a quadrature demodulated bit stream. Each byte should contains only one bit of information at the LSB.

propagated

Parameters

max_frame_len

the maximum allowed frame length

Returns

a shared pointer of the decoder instance

Constructor & Destructor Documentation

argos_ldr_decoder()

		size_t	max_frame_len = 64
	)

The decoder take as input a quadrature demodulated bit stream. Each byte should contains only one bit of information at the LSB.

Parameters

max_frame_len

Member Function Documentation

decode()

decoder_status_t gr::satnogs::argos_ldr_decoder::decode ( const void *  in, int  nitems  )

virtual

Decodes a buffer of input items contained in the in buffer. This method is called continuously by the frame_decoder. Based on the returned status data, the frame_decoder() instructs properly the GNU Radio scheduler and/or propagates decoded data.

As the number of input items may not enough to decode a frame, each decoder should keep internal state, so decoding can be accomplished after an arbitrary number of calls to this method

Parameters

in	the input items
nitems	the number of input items contained in the in buffer

Returns

the status of the decoder after the call of this method. For more information refer to decoder_status()

Implements gr::satnogs::decoder.

make()

static sptr gr::satnogs::argos_ldr_decoder::make ( bool  crc_check = true, size_t  max_frame_len = 64  )

static

reset()

void gr::satnogs::argos_ldr_decoder::reset ( )

virtual

Resets the internal state of the decoder to the initial defaults

Implements gr::satnogs::decoder.
