Simple real time frequency modulated continues wave radar built around USRP B210 software defined radio. Signal processing and detection is PC based mainly with GNU Radio and c++ application. Main purpose of this design is to establish reliable way of interfacing with USRP and using it with proprietary applications for real time radar software. Another reason was to design software for radar signal...
To provide efficient and effective mechanism for the network management it's necessary to create unified and flexible tool, independent from hardware solutions. Such tool could be set of policies, which control the behavior of radios, using predefined languages and parameters.
Ste gano graphic systems are used for the transmission of hidden data in the original signal. The article describes the algorithm of the hidden data transmission using the speech signal as a carrier. The echo method is used for data embedding. In order to improve the decoding efficiency of embedded data, the procedure of voicing correction and mechanism of informed coding were developed and implemented...
