Talvez deva tentar algumas variações de ortografia:
precoding rate » precoding based (Expandir a busca), precoding and (Expandir a busca), spreading rate (Expandir a busca)
rate decrease » rats decreases (Expandir a busca), ratio decrease (Expandir a busca), rate increase (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( precoding rate decrease _ program ) OR ( python code python python programming ))~.
