    • Systems (100) and methods for selectively controlling access to data streams communicated from a first communication device (FCD) using a timeslotted shared frequency spectrum and shared spreading codes. Protected data signals (1301, . . . , 130S) are modulated to form first modulated signals (1321, . . . , 132S). The first modulated signals are combined with first chaotic spreading codes to form digital chaotic signals. The digital chaotic signals are additively combined to form a protected data communication signal (PDCS). The PDCS (136) and a global data communication signal (GDCS) are time division multiplexed to form an output communication signal (OCS). The OCS (140) is transmitted from FCD (102) to a second communication device (SCD) over a communications channel. The SCD (106, 108, 110) is configured to recover (a) only global data from the OCS, or (b) global data and at least some protected data from the OCS.

    • A method, apparatus and computer program product for transmitting data secures the data by adaptively transforming it and spreading the transformed data piecewise over plural transmission channels. The method, apparatus and computer program product may select low-cost channels preferentially to transmit greater amounts of the data; may disorder the data and transmit ordering information separately over a preferred channel of higher security; may conceal data in a lower-security channel by steganographic methods; and may conceal the sequence of the data by placing segments of it statically, for example, in a WWW website, while providing sequencing data on the preferred channel of higher security. A receiving method, apparatus and computer program product may also be provided for recovering information content from signals on the plural channels.

    • A system for detecting and identifying the identity of a base station or cell which transmits a scrambling code is provided. According to one aspect of the system, the system is used to perform scrambling code detection of eight (8) primary cells (each scrambling code's X-component being spaced sixteen (16) chips apart) in a group. According to another aspect of the system, a single scrambling code generator is used to generate a master scrambling code. The master scrambling code is then used to create individual scrambling codes which are used in correlation with received signals to detect in parallel which one of the eight (8) possible primary cells in the group transmitted the received signals. According to yet another aspect of the system, each of the correlators maintains a corresponding X-component segment of the master scrambling code. For every sixteen (16) chips, a new X-component segment of the master scrambling code is introduced into one of the correlators, a X-component segment of the master scrambling code is dropped from another correlator, and X-component segments of the master scrambling code are sequentially shifted or propagated through the remaining correlators; and concurrent correlations are performed by the correlators using their respective corresponding X-component segments of the master scrambling code and newly received signals.
