Patent ID: 7035244

Claim:
A method for synchronization of an input-chip-sequence (x(ν)) of a CDMA-signal with a Pilot-Chip-Sequence (pn(ν)) having the following method steps: dividing the Pilot-Chip-Sequence (pn(ν)) into subintervals (1, 2, 3 . . . 8), assembling a particular number (2Anz sub ) of the subintervals (1, 2, 3 . . . 8) into subinterval groups, forming at least one summed subinterval group(s) (pn Σ1 (ν), . . . ), wherein the at least one summed subinterval group(s) is formed line-wise and pair-wise by arranging respective series of subintervals one-after-the-other (1,2; 2,3; 3,4 . . . 8,1), with the first subinterval of a particular line being respectively the second subinterval of the previous line, and column-wise adding the chips of all the line-wise, pair-wise, arranged subintervals (1,2; 2,3; 3,4; . . . 8,1); and correlating the input-chip sequence (x(ν)) with each summed subinterval group (pn Σ1 (ν), . . . ) in a first correlation ( 5 ; 5 a ; 5 b ) for determining a displacement (Ôffset) between the input-chip-sequence (x(ν)) and that of the respective summed subinterval group(s) (pn Σ1 (ν), . . . ).
