改进编码缓存的转换和间隙结果

Improved Converses and Gap Results for Coded Caching

Chien-Yi Wang, Shirin Saeedi Bidokhti, Michele Wigger

摘要:

改进的下界的平均值和最坏情况下的速率内存权衡的Maddah-Ali&Niesen编码的缓存方案。对于任意数量的用户和文件以及任意的缓存大小,在最坏情况下,精确的速率-内存折衷与新的下限之间的乘法差距小于2.315,在平均情况下小于2.507。

英文摘要:

Improved lower bounds on the average and the worst-case rate-memory tradeoffs for the Maddah-Ali&Niesen coded caching scenario are presented. For any number of users and files and for arbitrary cache sizes, the multiplicative gap between the exact rate-memory tradeoff and the new lower bound is less than 2.315 in the worst-case scenario and less than 2.507 in the average-case scenario.
