On the Partial Ordering of the Discrete Memoryless Channels Arising in Cooperative Sensor Networks

摘要: We focus on the open problem of partial ordering Discrete Memoryless Channel (DMC) in context cooperative sensor networks. In case binary DMCs we identify regions where DMC capacity is a Schur convex (concave) function under trace channel matrix constraint. Our approach based upon majorization theory connection with ordering. are able to give an answer for general symmetric DMCs. results generalize, and extend, previous work hold promise efficient network design.
