Claim:
A method for synchronizing a base station with a mobile station, the method comprising the steps of: forming a signal sequence K(i) at the base station, wherein the signal sequence K(i) is formed using the following rule using modulated repetition of a partial signal sequence “a” consisting of 16 elements: K=<a, a, a, −a, −a, a, −a, −a, a, a, a, −a, a, −a, a, a>, and wherein the signal sequence is further formed in accordance with the following relationship wherein a second partial signal sequence K 2 ( k ) of length n 2 =16 is repeated n 1 =16 times and is modulated in the process with a first partial signal sequence K 1 ( j ) of length n 1 =16, modulation of the second partial signal sequence K 2 ( k ) can be obtained using the following rule: K(i)=K 2 (i mod n 2 )*K 1 (i div n 2 ), for i=0 . . . n 1 *n 2 −1; forming at least one of the partial signal sequences, being a Golay sequence X n (k) of length nx=n 1 =16, using the following relationship: X′ 0 (k)=δ(k) X′ 0 (k)=δ(k) X n (k)=X n-1 (k)+W n *X′ n-1 (k−D n ) X′ n (k)=X n-1 (k)−Wn*X′ n-1 (k−D n ), k=0, 1, 2, . . . , 2 NX−1 n=1, 2, . . . , NX D n =2 Pn where nx=16=2 NX NX=4 δ(k): Kronecker delta function, and wherein the permutation P 1 , P 2 , P 3 , P 4 and unit variable W 1 , W 2 , W 3 , W 4 can be used to form a partial signal sequence from the following set of permutation/unit variable pairs (P 1 , P 2 , P 3 , P 4 , W 1 , W 2 , V 3 , W 4 ;): 3201, +1−1+1+1; 3201, −1−1+1+1; 3201, +1−1−1+1; 3201, −1−1−1+1; 3201, +1 −1+1−1; 3201, −1−1+1−1; 3201, +1−1−1−1; 3201, −1−1−1−1; 1023, +1+1−1+1; 1023, −1+1−1+1; 1023, +1−1−1+1; 1023, −1−1−1+1; 1023, +1+1−1−1; 1023, −1+1−1 −1; 1023, +1−1−1−1; 1023, −1−1−1−1; and transmitting the signal sequence K(i) from the base station to set up a synchronization with a mobile station.
