Feedback Capacity of the Gaussian Interference Channel to within 2 Bits
Changho Suh, David Tse
We characterize the capacity region to within 2 bits/s/Hz and the symmetric capacity to within 1 bit/s/Hz for the two-user Gaussian interference channel (IC) with feedback. We deve…
On the Existence of Optimal Exact-Repair MDS Codes for Distributed Storage
Changho Suh, Kannan Ramchandran
The high repair cost of (n,k) Maximum Distance Separable (MDS) erasure codes has recently motivated a new class of codes, called Regenerating Codes, that optimally trade off storag…
A Survey on Network Codes for Distributed Storage
Alexandros G. Dimakis, Kannan Ramchandran, Yunnan Wu +1
Distributed storage systems often introduce redundancy to increase reliability. When coding is used, the repair problem arises: if a node storing encoded information fails, in orde…
Downlink Interference Alignment
Changho Suh, Minnie Ho, David Tse
We develop an interference alignment (IA) technique for a downlink cellular system. In the uplink, IA schemes need channel-state-information exchange across base-stations of differ…
Exact Regeneration Codes for Distributed Storage Repair Using Interference Alignment
Changho Suh, Kannan Ramchandran
The high repair cost of (n,k) Maximum Distance Separable (MDS) erasure codes has recently motivated a new class of codes, called Regenerating Codes, that optimally trade off storag…
