Abstract :
This paper proposes the analog circuits for implementing soft decoding algorithms. Importance sampling permits evaluation of analog designs using precise physical models in SPICE simulations. SPICE provides extremely accurate circuit simulations, but requires large simulation time. This allows evaluation and optimization of analog decoder designs. With importance sampling, the decoder´s performance can be accurately estimated for any SNR.
