global_information_extractor: This model is trained using a transformer encoder and decoder architecture, based on the configuration specified in Donut, to extract the overall summary of block diagram ...

Especially in the encoded case, as the BER doesnt seem to improve with the encoder. For the QAM and 16QAM the encoded plot looks better, as an improvement is visible, in contrast to the uncoded case.

This chapter summarizes digital communications theory from encoder and modulator through demodulator and decoder. It provides a block diagram of the satellite communications channel, showing elements ...

The encoder takes a block of 168 data bytes, (conceptually) adds 55 zero bytes, creates a (255,223) codeword and transmits only the 168 data bytes and 32 parity bytes. The amount of processing "power" ...
