METHOD AND SYSTEM FOR DETECTING A FIRST SYMBOL SEQUENCE IN A DATA SIGNAL, METHOD AND SYSTEM FOR GENERATING A SUB-SEQUENCE OF A TRANSMISSION SYMBOL SEQUENCE, AND COMPUTER PROGRAM PRODUCTS

摘要

A method for detecting a first symbol sequence in a data signal is described comprisingreceiving the data signal in which the first symbol sequence should be detected,wherein the first symbol sequence is expressable as the kronecker product ofa second symbol sequence and a third symbol sequence; correlating the first symbolsequence with the third symbol sequence to generate a first correlation resugenerating a second correlation result by correlating a fourth symbol sequencederived from the first correlation result with a fifth symbol sequence derivedfrom the second symbol sequence by a transformation that maps all negative symbolsof the second symbol sequence to non-negative symbols; and generating a detectionresult based on the second correlation result.
