The Exact Capacity-Memory Tradeoff for Caching with Uncoded Prefetching in the Two-Receiver Gaussian Broadcast Channel
Mohamed Salman, Mahesh K. Varanasi · 2019
The two-receiver Gaussian broadcast channel (BC) is studied when each receiver has a cache memory. Using a joint cache-channel coding scheme, the exact capacity-memory tradeoff-the highest rate of reliable communication as a function of the cache size-is established for any cache size.
