Polar codes are optimal for lossy source coding
We consider lossy source compression of a binary symmetric source using polar codes and the low-complexity successive encoding algorithm. It was recently shown by Arikan that polar...

Large developing receptive fields using a distributed and locally reprogrammable address-event receiver
A distributed and locally reprogrammable address event receiver has been designed, in which incoming addressevents are monitored simultaneously by all synapses, allowing for arbitr...

Zero leakage quantization scheme for biometric verification
Biometrics gain increasing interest as a solution for many security issues, but privacy risks exist in case we do not protect the stored templates well. This paper presents a new ...

Hardware architectures for successive cancellation decoding of polar codes
The recently-discovered polar codes are widely seen as a major breakthrough in coding theory. These codes achieve the capacity of many important channels under successive cancella...

Performance analysis of optimal beamforming in MIMO dual-hop amplify-and-forward systems
This paper presents an analytical investigation on the performance of optimal beamforming scheme in multiple-input multiple-output dual-hop amplify-and-forward systems. We first ...
