Abstract: Disclosed herein are methods and systems that apply a multi-layer Hidden Markov Model (HMM) for intrusion detection. The methods and systems employ a dimension reduction technique to extract only important features from network packet data and apply a decomposition algorithm to lower levels of data to construct lower level HMMs (representing partial solutions), which lower level HMMs are then combined to form a final, global solution. The multi-layer approach can be expanded beyond the exemplary case of 2 layers in order to capture multi-phase attacks over longer spans of time. A pyramid of HMMs can resolve disparate digital events and signatures across protocols and platforms to actionable information where lower layers identify discrete events (such as network scan) and higher layers identify new states which are the result of multi-phase events of the lower layers.

Abstract: Systems and methods are provided for transmitting OFDM signals through a communication channel exhibiting frequency selective fading, such as an aeronautical 2-ray channel, using a signal modulation scheme at the transmitter that is selected based on a measurement of signal to distortion ratio (SDR) at the receiver. The SDR measurement at the receiver is used to generate an estimated best modulation scheme based on the real-time detection and measurement of SDR at the receiver, and provide feedback to the transmitter through a feedback channel of the newly selected modulation scheme. In certain configurations, the selected modulation scheme is one of multiple possible quadrature amplitude modulation (QAM) schemes, which enables adaptation of the transmitted OFDM signal to optimize throughput based on distortion of individual tones of the OFDM signal received at the receiver.

Abstract: Systems and methods are provided for reducing peak-to-average power ratio (“PAPR”) in an orthogonal frequency division multiplexing (“OFDM”) signal having reference tones by introducing modified pilot tones to cancel peaks in OFDM symbols in the OFDM signal array. The modified pilot tones are added to the original OFDM signal, which in turn conditions the OFDM symbols of the signal to effectively reduce the PAPR. Such systems and methods provide PAPR reduction for OFDM signals generated by an OFDM Signal Processor through the addition of tone reservation PAPR reduction methods, which use reserved tones such as pilot tones to improve PAPR. Such methods offer an advantage of improving the PAPR without introducing distortion to the signal.
