Transmitter-directed security for wireless-communications
First Claim
Patent Images
1. A method of transmitter-directed transmission security in a wireless communication link, the method comprising:
- accepting data for transmission from a data source at a transmitter;
forming data frames and inserting at least a portion of the data into the data frames;
selecting a transmission format for each data frame based on a transmission security scenario, wherein the transmission format changes between at least one pair of data frames;
communicating format information from the transmitter to a receiver, the information at least partially defining the transmission format of each data frame; and
transmitting each data frame from the transmitter to the receiver on the wireless communication link using the corresponding transmission format.

Abstract
Transmitter-directed transmission security is provided between a transmit node and a receive node. The transmit node selects transmission format for each data frame based on a transmission security scenario. Information related to the transmission format is communicated between the transmit node and the receive node, and the data frames are transmitted over a wireless communication link using the selected transmission formats.

18. A wireless transmission system providing transmitter-directed transmission security, comprising:
-
a framer having a data input and frame output and configured to form and output data frames using data received at the data input; a selector coupled to the framer and configured to select a corresponding transmission format for each data frame based on a transmission security scenario; and a transmitter coupled to the framer and the selector, the transmitter configured to transmit format information into a wireless channel that at least partially defines the transmission format and configured to transmit the data frames into the wireless channel using the corresponding transmission format. - View Dependent Claims (19, 20, 21, 22, 23)

24. A wireless reception system using transmitter-directed transmission security, comprising:
-
a first receiver configured to receive over a wireless communications link format information that at least partially defines a transmission format of data frames; a decoder coupled to the first receiver and configured to use the format information to determine a frame format of the data frames; and a second receiver coupled to the decoder and configured to receive the data frames over the wireless communications link using the frame format determined by the decoder. - View Dependent Claims (25, 26, 27, 28, 29)
