    摘要: A communication method in an adaptive CDMA communication system (100) capable of communicating a direct sequence spread spectrum communication signals which comprise bit sequences coded with spreading chip sequences. The method includes the steps of transmitting a DS-SS communication signal (30) having a training bit sequence (31) coded with spreading chip sequence. The method includes the step of despreading the DS-SS communication signal based on the training bit sequence (31) during a training interval. The DS-SS communication signals is despread by adaptively determining a despreading chip sequence. Then, following the training interval determining chip timing offset during a chip timing interval. Finally, bit timing offset is determined during a bit timing interval following the chip timing interval.

    摘要: In a CDMA communication system (100) capable of communicating between a receiver (20) and a transmitter (10) direct sequence spread spectrum communication signals (30), a system and method for synchronizing receiver bit timing and transmitter timing. Transmitter (10) transmits a training bit sequence (31) followed by a transmitter bit timing sequence (33). The receiver (20) adaptively determines a representation of a despreading chip sequence using a tapped delay line equalizer (400). Receiver bit timing offset is determined based on the representation of the despreading chip sequence and the transmitter bit timing sequence (33).

    摘要: A correlated magnetic assembly for securing objects in a vehicle includes an object that incorporates a first field emission structure and a surface within the vehicle that incorporates a second field emission structure. The first and second field emission structures each include an array of field emission sources each having positions and polarities relating to a desired spatial force function that corresponds to a complementary alignment of the first and second field emission structures within a field domain. The object is attached to the surface of the vehicle when the first and second field emission structures are located next to one another and have a complementary alignment with respect to one another.
