The common-mode (CM) signal in wireline transmission systems has proven to provide valuable information exploited for mitigating narrowband noise at the receive side. In this paper, we focus on the case of broadband noise. Treating the CM signal as an additional receive signal, we investigate the capacity of the copper cable channel for different levels of coordination among the users. We intro...

This paper contains a construction for independent sets in the powers of the complements of odd cycles. In particular, we show that α ( C 2 2n+3 ) ≥ 22n + 1. It follows that for n ≥ 0 we have Θ(C2n+3) > 2, where Θ(G) denotes the Shannon capacity of graph G.

It has recently been demonstrated that zero correlation of a random multiple-input multiple-output channel is not a guarantee of its high capacity. Degenerate channels exist, which have zero correlation and still low capacity. In this letter, we provide a statistical analysis of this phenomenon, formulate the general condition for a channel to be degenerate, and propose a method to estimate its...

Abstract—In this paper we consider the identification (ID) via multiple access channels (MACs). In the general MAC the ID capacity region includes the ordinary transmission (TR) capacity region. In this paper we discuss the converse coding theorem. We estimate two types of error probabilities of identification for rates outside capacity region, deriving some function which serves as a lower bou...

Abstract Integration relies on a series of key change strategies connected by a fundamental dynamic: system capacity has to match demand or it will ultimately result in expanding delay and system failure. A balance of supply and demand is necessary for successful system performance. If demand and capacity are balanced, then delays are not required. Process Improvement and Supply and Demand: The...

Any capacity (i.e., an increasing set function) has been proved to be a lower possibility measure and an upper necessity measure. Similarly, it is shown that any anti-capacity (i.e., a decreasing set function) can be viewed both as an upper guaranteed possibility measure and as a lower weak necessity measure. These results are the basis for establishing that qualitative integrals (including Sug...

The paper asks how a for-profit cable or satellite operator allocates a fixed channel capacity to different program types and how the different channels are bundled and priced. It also addresses the question how channel allocation and bundling decisions made by a for-profit firm differ from the decisions a welfare-maximizing firm would make. It also examines the effect on profits and welfare of...

Abstract—We consider the state dependent channels with full state information with at the sender and partial state information at the receiver. For this state dependent channel, the channel capacity under rate constraint on the state information at the decoder was determined by Steinberg. In this paper, we study the correct probability of decoding at rates above the capacity. We prove that when...
