On tractable wireless channel models

摘要: We present techniques to capture the behavior of realistic channels with mathematically tractable models, examine different state-space aggregation reduce a large number states Markov chain fewer states, The property strong and weak lumpability is discussed stochastic bounding are examined. These applied three types previously published channel models for mobile VHF, wireless indoor, Rayleigh fading channels. Results show that our technique can produce simpler yet still accurate upper bound original model. find bounds perform well when higher-layer error control protocols such as stop-and-go TCP considered.
