Abstract
Apparatus for vector generation is described. A vector generator is associated with a discrete power series symmetric about at least one term and configured to provide vectors, such as QSvectors for a Turbo Code for example. The vectors are each provided in separate portions as a first portion and a second portion. The second portion of a vector of the vectors is generated from the first portion of the vector using symmetry about the at least one term.

An interleaver, comprising:
- a read address generator including:
- a vector generator, the vector generator associated with a discrete power series, the discrete power series being symmetric about at least one term;
- the vector generator configured to provide vectors;
- the vectors each being provided in separate portions as a first portion and a second portion;
- and
- the second portion of a vector of the vectors generated from the first portion of the vector using symmetry about the at least one term.
3 more elements
An apparatus for use associated with multi-channel interleaved data, comprising:
- a vector generator configured to provide a first portion of each of a plurality of vectors, the vectors being associated with a discrete power series for a type of error-correcting code, the discrete power series being symmetric about at least one term;
- and
- term manipulation circuitry coupled to receive the first portion and configured to provide a second portion of each of the vectors responsive to the first portion of each of the vectors using symmetry about the at least one term of the discrete power series.
