... (Concatenation of Nodes). Assume a flow traverses systems S 1 and S 2 in sequence. Assume that S i offers a maximum service curve of γ i , i =1, 2 to the flow. Then the concatenation of the two systems offers ... follows. Consider a network, made of a series of network elements 1, , I, each element being the combination of a fixed delay d i and a variable delay. Assume the variable delay component offers a service ... Then the concatenation of the two systems offers a service curve of γ 1 ⊗ γ 2 to the flow. P ROOF: The proof mimics the proof of Theorem 1.4.6 APPLICATION: Consider a node with a maximum output...

... these results are derived for rather unrealistic models of cellular systems. A complementary body of work on network MIMO focuses on the performance evaluation of specific system architectures and signal processing ... overview of several approaches to handling interference in cellular systems, including network MIMO. The aforementioned studies have shown that network MIMO indeed holds the promise of very large ... wireless systems. Our focus in this paper is on network MIMO, a family of techniques whereby each end user in a wireless access network is served through several access points within its range of influence....
