Patent ID: 6920183

Claim:
An apparatus to communicate a set of data symbols d(i) where i=1, . . . , n, where n is a positive integer greater than one, the apparatus comprising: a set of transmission lines l(i) where i=1, . . . , n, where transmission line l(i) propagates a signal x(i) for i=1, . . . , n; a set of receivers r(i) where i=1, . . . , n, wherein receiver r(i) is connected to transmission line l(i) to receive the signal x(i) for each i=1, . . . , n; a set of drivers t(i) where i=1, . . . , n, where driver t(i) is connected to transmission line l(i) to transmit the signal x(i) for each i=1, . . . , n; and a mapper to map the set of data symbols d(i) to the signals x(i) for i=1, . . . , n, wherein for each i=1, . . . , n, x(i) is a function of d(i) and at least one d(j) for j≠i; wherein for each i=1, . . . , n, receiver r(i) provides an estimate of d(i) based upon the signal x(i) independently of x(j) for j≠i.
