Publish in transactions/reputed journals

Is it required to create a new block to publish in a reputed
journals/transactions regarding GNU Radio?

In GNU Radio, almost 200 signal processing blocks are available. Till
now, I have done my work by using those only. But now I want to submit
for reputed journals/transactions? Is it possible to write a paper by
using available blocks only? Could you please let me know? Any answers
are appreciated.
