Title:

FAST DECODING OF LONG CODES

Document Type and Number:

WIPO Patent Application WO2002049229

Kind Code:

A3

Abstract:

A method and apparatus for long code group determination. The long code group is determined based upon a number of symbols in a received codeword, wherein the number of symbols is less than the total number of symbols in the codeword. The long code group number can be determined either through the use of a table of code sequences or through a reduced complexity code search. The use of the of these techniques allows for a quick determination of the long code group used by a particular base station.
