摘要： A system and method for providing variable security levels in a wireless communication network. The present invention optimizes the often conflicting demands of highly secure wireless communications and high speed wireless communications. According to a preferred embodiment of the present invention, various security sensors are scanned to determine the likely presence of an intruder within a predetermined trust zone. If an intruder is likely present, the security level is changed to the highest setting, and consequently a lower data rate, while the intruder is identified. If the identified intruder is in fact a trusted node, the security level is returned to a lower setting. If the identified intruder is not a trusted node, the security level is maintained at an elevated state while the intruder is within the trust zone.

摘要： A method and apparatus for securing wireless communications are disclosed. A watermark message is encoded to watermark message symbols. A cover message is encoded to cover message symbols. The watermark message symbols are then overlaid onto the cover message symbols to generate a watermark-embedded cover message in a physical layer. The watermark message symbols have a substantially lower amplitude than the cover message symbols. Thus, the watermark message introduces small perturbation around the constellation points of the cover message symbols. The watermark message symbol may span or spread over a plurality of cover message symbols and may be encrypted with a secret key. The watermark message is used for improving receiver performance by transmitting additional information or for security enhancement purposes. The watermarking function may be selectively turned on and off.
摘要翻译：公开了一种用于确保无线通信的方法和装置。水印消息被编码为水印消息符号。封面信息被编码以覆盖消息符号。然后将水印消息符号覆盖到封面消息符号上，以在物理层中生成嵌入水印的封面消息。水印消息符号具有比覆盖消息符号大得多的幅度。因此，水印消息在覆盖消息符号的星座点周围引入小的扰动。水印消息符号可以覆盖多个封面消息符号并且可以用秘密密钥加密。水印消息用于通过发送附加信息或为了安全增强目的来改善接收机性能。可以选择性地打开和关闭水印功能。

摘要： The present invention is related to a method and apparatus for enhancing security of communications. The apparatus comprises a security processing unit, a data processing unit, a cross-layer watermarking unit, and optionally a smart antenna processor. The security processing unit generates a token/key to be used in watermarking and sends a node security policy to other components. The data processing unit generates user data. The cross-layer watermarking unit includes at least one of Layer-2/3, Layer-1 and Layer-0. Each layer performs a different scheme or degree of watermarking. The cross-layer watermarking unit embeds the token/key into the user data transmission on at least one of the layers selectively in accordance with a security policy.

摘要： The present invention is a method and apparatus for improving the performance of spatial temporal turbo channel coding (STTCC) used in multiple-input multiple-output (MIMO) wireless communication systems called eigen-STTCC (E-STTCC) that employs eigen-beamforming to make use of orthogonal eigen streams in the MIMO channel. Singular value decomposition (SVD) is applied to the channel matrix producing a linear precoding matrix containing the orthonormal basis for the eigen streams. In a first embodiment, the turbo encoded codeword containing concatenated systematic and parity bits is precoded with the linear precoding matrix such that the systematic bits are transmitted over the eigen streams with highest power. In a second embodiment, the codeword is made up of interleaved systematic bits and parity bits prior to eigen beamform preceding, effectively interleaving the systematic and data bits spatially over the eigen streams. In an alternate embodiment, the data stream is interleaved at the input to the encoder.
