Abstract

See full text

An inversion circuit (212) determines an inverse B.sup.-1 of an m-bit symbol B, the symbol B being expressed in a dual basis representation. Inversion circuit (212) includes an iterative convolution circuit (124A, 124B, 124C) to which the symbol B is applied and which generates and stores electrical signals corresponding to an m-bit value A. The value A is in a first basis representation and is generated by the convolution circuit such that an inner product of A and .alpha..sup.k B is equal to 0 for k
