Abstract
A method of generating an interleaved symbol sequence location from a symbol location of a symbol sequence comprises determining the interleaved symbol location based on an interleaver sequence function which relates a linear symbol location to the interleaved symbol location. This is done by acquiring values of the interleaver sequence function in quotient and remainder form and then calculating the interleaved symbol location by performing operations of the interleaver sequence function in quotient and remainder form.

A method of generating an interleaved symbol location from a linear symbol location of a symbol sequence comprising:
- determining the interleaved symbol location based on an interleaver sequence function which relates a linear symbol location to the interleaved symbol location by:
- acquiring parameters of the interleaver sequence function in quotient and remainder form;
- calculating the interleaved symbol location by performing operations of the interleaver sequence function in quotient and remainder form;
- and
- outputting the determined interleaved symbol location.
An interleaver for generating an interleaved symbol location from a linear symbol location of a symbol sequence comprising:
- a processing circuit configured to determine the interleaved symbol location based on an interleaver sequence function which relates a linear symbol location to the interleaved symbol location by:
- acquiring parameters of the interleaver sequence function in quotient and remainder form;
- and
- calculating the interleaved symbol sequence location by performing operations of the interleaver sequence function in quotient and remainder form,
- wherein the processing circuit is further configured to output the determined interleaved symbol location.
