    • An apparatus for identifying a specific emitter in the presence of noise and/or interference is disclosed. The apparatus includes a sensor configured to sense radio frequency signal data, the signal data containing noise and signal from at least one emitter, a reference estimation unit configured to estimate a reference signal relating to the signal transmitted by one emitter, a feature estimation unit configured to generate one or more estimates of one or more feature from the reference signal and the signal transmitted by that particular emitter, and an emitter identifier configured to identify the signal transmitted by that particular emitter as belonging to a specific device using one or more feature estimates. The emitter identifier identifies the signal transmitted by that particular emitter as belonging to a specific device using Gaussian Mixture Models and the Bayesian decision engine. The apparatus may also include an SINR enhancement unit configured to enhance the SINR of the data before the reference estimation unit estimates the reference signal.

    • The present disclosure is directed to a system and method for providing directional spectral awareness via an antenna system which includes a single parasitic antenna and a processor, the processor being communicatively coupled with the parasitic antenna. The antenna system allows for quick scanning of all sectors included in a plurality of sectors of an RF environment being monitored by the antenna system. The antenna system also allows for monitoring sectors of interest. The directionality of the parasitic antenna of the antenna system may reduce interference and multipath along with providing improved SNR due to antenna gain, thereby allowing for collection of signals of interest in a more favorable environment, thereby enabling analysis such as frequency and spatial use, signal detection, signal identification, and source geolocation to succeed when it may have failed if an omni-directional antenna were used.

    • An orthogonal frequency division multiplexing (OFDM) communications system transmits data on a plurality of subcarriers and has a featureless synchronization signal. The OFDM communications system transmits synchronization tones on pseudorandomly selected subcarriers. A receiver generates the same synchronization tones and performs a correlation on the received signal with the receiver synchronization tones. The correlation is performed at the beginning and the end of the synchronization symbol. A product of the two correlations results in a magnitude peak and a phase difference. The magnitude peak is used to determine the location in time of the sync symbol and the phase difference is used to determine the frequency offset of the received signal.
    • 正交频分复用(OFDM)通信系统在多个子载波上发送数据并具有无特征同步信号。 OFDM通信系统在伪随机选择的子载波上发送同步音调。 接收机产生相同的同步音,并且用接收机同步音进行接收信号的相关。 相关性在同步符号的开始和结束时执行。 两个相关的乘积导致幅度峰值和相位差。 幅度峰值用于确定同步符号的时间位置,并且使用相位差来确定接收信号的频率偏移。

    • A method for transmitting data from a transmitter to a receiver in an ad hoc large scale directional network includes the followings steps. A first training sequence is sent by a transmitter in an ad hoc directional network. The first training sequence is received by a receiver in the ad hoc directional network. The receiver determines a first apparent direction from which the first training sequence is sent. The receiver sends a second training sequence to the transmitter. The transmitter determines a second apparent direction from which the second training sequence is sent. The transmitter directs a signal with the first training sequence to the receiver. The transmitter sends the signal with the first training sequence to the receiver. The receiver receives the first training sequence. The receiver is directed to the first apparent direction to receive the signal.
