Near-Capacity Iteratively Decoded Space-Time Block Coding
— Iteratively decoded near-capacity Space-Time Block Coding (STBC) schemes are designed. Recursive unity-rate codes and IRregular Convolutional Codes (IRCCs) are employed for ass...

Time-Domain Spreading And Frequency-Domain Spreading for Delay-time/Code Division Multi-Access
—The uplink (mobile-to-base) bit error rate (BER) performance is significantly degraded due to the multi-access interference (MAI). Recently, we have proposed a new hybrid multi-...

Unidirectional Key Distribution Across Time and Space with Applications to RFID Security
We explore the problem of secret-key distribution in unidirectional channels, those in which a sender transmits information blindly to a receiver. We consider two approaches: (1) ...

Managing WIP and cycle time with the help of Loop Control
As an adaptation of the CONWIP concept, AMD has developed a heuristic approach to control the WIP in its wafer fabrication facilities (fabs). The so called "Loop Control"...
