On the mobile wireless access via MIMO relays

Tae Hyun Kim, Nitin H. Vaidya, Young-Bae Ko
2009 2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications  
While the introduced hardware complexity improves the throughput in low and moderate SNR regime, the throughput is improved by relay scheduling for spatial reuse in high SNR regime.  ...  This happens due to quick channel variation and its resulting protocol overheads that are especially large for multiuser multiple-input multiple-output (MIMO) systems.  ...  The time-sharing penalty for high SNR users is still expensive even with more antennas at the relay. • Spatial reuse gains: The MIMO relay gains so far come from the additional hardware complexity in the  ...

Memory forwarding

Chi-Keung Luk, Todd C. Mowry
1999 SIGARCH Computer Architecture News  
By optimizing data layout at run-time, we can potentially enhance the performance of caches by actively creating spatial locality, facilitating prefetching, and avoiding cache conflicts and false sharing  ...  To overcome this limitation, we propose a technique called memory forwarding which effectively adds a new layer of indirection within the memory system whenever necessary to guarantee that data relocation  ...  Acknowledgments We thank Daniel Meneveaux for providing his radiosity program.
