Modelling the Relationship between Visual Short-Term Memory Capacity and Recall Ability
Previous cognitive modelling work has suggested that the decline of short-term memory (STM) capacity is the dominant factor of age-related decline on recall ability. We report the...

Two-Way Relaying over OFDM: Optimized Tone Permutation and Power Allocation
—We consider an amplify-and-forward scheme for two-way relaying over OFDM, in which two nodes wish to exchange information via a relay. Assuming full channel knowledge, we perfor...
