To increase the achievable sum rate of downlink MIMO (Multiple Input Multiple Output) systems, the cooperation among Base Stations (BS) is investigated in a slow fading channel. Th...
Adoption of relay stations has been commonly accepted as a key technique for future IMTadvanced 4G systems to improve the link performance. While study in relay systems is often c...
We studied CAD system users to find out how they use the sophisticated customization and extension facilities offered by many CAD products. We found that users of varying levels o...
