Can some one please help me on the AAS preamble code construction
defined in the section 8.4.4.7.9.6 part of the section that the
The AAS preamble is a constant modulus BPSK code unique to a given
base station defining the AASregion of the frame. The code uses
nonlinear phase construction and is uncorrelated to the codes used by
the other bases. Furthermore, the codeword in the second AAS preamble
symbol slot does not resemble a complex scalar multiplying the
codeword in the first AAS preamble symbol slot. The code is split into
two codewords for the two AAS symbol slots in a forward link. Each
length 16 codewords modulates the data subcarriers in two adjacent
bins (a bin pair).
What is the nonlinear phase construction sequence & how is it chosen
the sequence was defined for the SC-a section but wasn't defined for
the OFDMA section.
with regards
srikanth
