The Capacity Region of the Discrete Memoryless Interference Channelwith Strong Interference
Capacity Region Discrete Memoryless Interference Channelwith Strong Interference
2015/8/12
The capacity region of the discrete memoryless interference channel with strong interference is established.
A computer memory with defects is modeled as a discrete memoryless channel with states that are statistically determined. The storage capacity is found when complete defect information is given to the...
Bounds on Capacity and Minimum Energy-Per-Bit for AWGN Relay Channels
Additive white Gaussian noise (AWGN) channels channel capacity minimum energy-per-bit relay channel
2015/8/12
Upper and lower bounds on the capacity and minimum energy-per-bit for general additive white Gaussian noise (AWGN) and frequency-division AWGN (FD-AWGN) relay channel models are established. First, th...
Geometric programming duals of channel capacity and rate distortion
Channel capacity convex optimization duality free energy geometric programming rate distortion
2015/8/11
We show that the Lagrange dual problems of the channel capacity problem with input cost and the rate distortion problem are simple geometric programs. Upper bounds on channel capacity and lower bounds...

2013/1/28
We consider a network of computer data centers on the earth surface delivering computing as a service to a big number of users. The problem is to assign users to data centers to minimize the total com...
PacketTwins: A Novel Method for Capacity Estimation of a Heavy-Loaded Path
PacketTwins Capacity Estimation Heavy-Loaded Path
2009/9/4
We propose a method called PacketTwins for estimating the capacity of heavy-loaded paths. Unlike popular packet pair methods, which probe a path with a series of two equal-sized packets, PacketTwins u...
Blood-Cell-Sized Memory Device Beats Industry Estimates for Computing Capacity（图）
blood cell molecular computers
2007/1/26
January 25, 2007，Researchers have created an ultra-dense memory device the size of a white blood cell that has enough capacity to store the Declaration of Independence and still have space left over. ...
