  • Patent number: 6674790
    Abstract: A system and method for enabling a transmitter employing signal spreading techniques to increase the data rate of the transmitted modulated signal without reducing the multi-path delay spread. Specifically, the system and method use concatenated spreading sequences to provide data modulated spread signals having increased data rates with extended multi-path delay spread. The system and method therefore removes the one-to-one relationship between the repetitive spreading code length and maximum multi-path delay spread of a data modulated spread signal, to thus increase the data rate for a given multi-path delay spread while preserving the autocorrelation and cross-correlation properties of the individual spreading sequences.

  • Patent number: 6580981
    Abstract: A system and method for sending and receiving messages, such as status or request-for-help messages, automatically between mobile nodes and ultimately to an appropriate destination via a wireless infrastructure. When a node determines that such infrastructure is not available, the node will communicate the necessary information to another mobile node located in, for instance, a vehicle. In this case, the receiving node stores the information, then transmits the information from that node to the wireless infrastructure equipment, so that the infrastructure can forward the message to an appropriate destination once such equipment is in range of this second node.
