Talvez deva tentar algumas variações de ortografia:
demodulation algorithm » demodulation algorithms (Expandir a busca), modulation algorithm (Expandir a busca), simulation algorithm (Expandir a busca)
coder demodulation » code modulation (Expandir a busca), coded modulation (Expandir a busca), power modulation (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
algorithm in » algorithm and (Expandir a busca), algorithm _ (Expandir a busca), algorithm with (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder demodulation algorithm in ) OR ( _ python python python programming ))~.
