Detailed Description

A rate 1/2, k=7 convolutional encoder for the CCSDS standard

This block performs convolutional encoding using the CCSDS standard polynomial ("Voyager").

The input is an MSB first packed stream of bits.

The output is a stream of symbols 0 or 1 representing the encoded data.

As a rate 1/2 code, there will be 16 output symbols for every input byte.

This block is designed for continuous data streaming, not packetized data. There is no provision to "flush" the encoder.
