Abstract: Embodiments of the present disclosure provide a transmitter, a receiver and methods of operating a transmitter and a receiver. In one embodiment, the transmitter includes a synchronization unit configured to provide a primary synchronization signal and a secondary synchronization signal having first and second segments. The transmitter also includes a secondary scrambling unit configured to provide a scrambled secondary synchronization signal, wherein scrambling agents for the first and second segments are derived from a primary synchronization sequence of the primary synchronization signal. The secondary scrambling unit is further configured to provide an additional scrambling of one of the first and second segments, wherein a second scrambling agent is derived from the remaining segment of a secondary synchronization sequence of the secondary synchronization signal. The transmitter further includes a transmit unit configured to transmit the primary synchronization signal and the scrambled secondary synchronization signal.

Abstract: Embodiments of the present disclosure provide a transmitter, a receiver and methods of operating a transmitter and a receiver. In one embodiment, the transmitter includes a synchronization unit configured to provide a primary synchronisation signal and a secondary synchronisation signal having first and second segments. The transmitter also includes a secondary scrambling unit configured to provide a scrambled secondary synchronization signal, wherein scrambling agents for the first and second segments are derived from a primary synchronization sequence of the primary synchronization signal. The secondary scrambling unit is further configured to provide an additional scrambling of one of the first and second segments, wherein a second scrambling agent is derived from the remaining segment of a secondary synchronization sequence of the secondary synchronization signal. The transmitter further includes a transmit unit configured to transmit the primary synchronization signal and the scrambled secondary synchronization signal.

Abstract: Embodiments of the present disclosure provide a transmitter, a receiver and methods of operating a transmitter or a receiver. In one embodiment, the transmitter is for use with a base station and includes a primary module configured to provide a primary synchronization signal. The transmitter also includes a secondary mapping module configured to provide a secondary synchronization signal derived from two sequences taken from a same set of N sequences and indexed by an index pair (S1, S2) with S1 and S2 ranging from zero to N−1, wherein the index pair (S1, S2) is contained in a mapped set of index pairs corresponding to the same set of N sequences that defines a cell identity group. Additionally, the transmitter further includes a transmit module configured to transmit the primary and secondary synchronization signals.
