Have you heard the saying “the problem is the solution”? It seems to originate in the permaculture movement, but it can apply equally well to electronics. Take the problem [shiura] ...

Abstract: To address the problem of high complexity of channel estimation for orthogonal time frequency space (OTFS) systems, we propose a low complexity channel estimation method leveraging the ...

Abstract: A radio frequency (RF) power amplifier (PA) plays an important role to amplify the message signal at higher power to transmit it to a distant receiver. Due to a typical nonlinear behavior of ...
