Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 5:
6. A device comprising:
a signal generator coupled with a data processor and configured to:
generate a pseudo-random sequence c(i) defined by

c(i)=(x(i+Nc)+y(i+Nc))mod 2

x(i+31)=(x(i+3)+x(i))mod 2

y(i+31)=(y(i+3)+y(+2)+y(i+1)+y(i))mod 2

where x(i) and y(i) are m-sequences and Nc is a constant; and
generate a reference signal sequence based on the pseudo-random sequence, and
a transmit circuitry configured to transmit the reference signal sequence,
wherein the pseudo-random sequence c(i) is initialized with an initial value obtained by using (2 NIDcell+1), where NIDcell is a cell identifier of the cell.
