B.1 Alternative generation
25.2233GPPRelease 17Spreading and modulation (TDD)TS
The generalised hierarchical Golay sequences for the PSC described in 7.1 may be also viewed as generated (in real valued representation) by the following methods:
Method 1.
The sequence y is constructed from two constituent sequences x1 and x2 of length n1 and n2 respectively using the following formula:
– y(i) = x2(i mod n2) * x1(i div n2), i = 0 … (n1* n2) – 1.
The constituent sequences x1 and x2 are chosen to be the following length 16 (i.e. n1 = n2 =16) sequences:
– x1 is defined to be the length 16 (N(1)=4) Golay complementary sequence obtained by the delay matrix D(1) = [8, 4, 1,2] and weight matrix W(1) = [1, -1, 1,1].
– x2 is a generalised hierarchical sequence using the following formula, selecting s=2 and using the two Golay complementary sequences x3 and x4 as constituent sequences. The length of the sequence x3 and x4 is called n3 respectively n4.
– x2(i) = x4(i mod s + s*(i div sn3)) * x3((i div s) mod n3), i = 0 … (n3* n4) – 1.
– x3 and x4 are defined to be identical and the length 4 (N(3)= N(4)=2) Golay complementary sequence obtained by the delay matrix D(3) = D(4) = [1, 2] and weight matrix W(3) = W(4) = [1, 1].
The Golay complementary sequences x1,x3 and x4 are defined using the following recursive relation:
a0(k) = (k) and b0(k) = (k);
an(k) = an-1(k) + W(j)n·bn-1(k–D(j)n);
bn(k) = an-1(k) – W(j)n·bn-1(k–D(j)n);
k = 0, 1, 2, …, 2**N(j) -1;
n = 1, 2, …, N(j).
The wanted Golay complementary sequence xj is defined by an assuming n=N(j). The Kronecker delta function is described by , k,j and n are integers.
Method 2
The sequence y can be viewed as a pruned Golay complementary sequence and generated using the following parameters which apply to the generator equations for a and b above:
(a) Let j = 0, N(0) = 8.
(b) [D10,D20,D30,D40,D50,D60,D70,D80] = [128, 64, 16, 32, 8, 1, 4, 2].
(c) [W10,W20,W30,W40,W50,W60,W70,W80] = [1, -1, 1, 1, 1, 1, 1, 1].
(d) For n = 4, 6, set b4(k) = a4(k), b6(k) = a6(k).
