Abstract
Structured Channel Signaling (SCS) is a technique for designing signals and receivers in a way that is well suited to parallel processing in high speed transmission circuits. This paper reviews and extends some of the theory behind SCS and shows that it subsumes linear noise cancellation in its application, thus explaining the robustness of SCS systems in the presence of impulse noise. It is also shown how the theory of noise cancellation is related to that of SCS. It is shown that the capacity of a broad class of infinite-dimensional channels is realized by using only a finite-dimensional signaling alphabet. SCS is applied to give a new explanation of the effectiveness of fractionally spaced equalizers. It is also shown how SCS might be used to effectively provide some of the benefits of diversity in tetherless access systems.
