Noise radar is a very promising technology offering advantages which cannot be achieved in classical radar systems. Unfortunately, it has also several disadvantages. One of the most significant is the masking effect, where strong objects raise the noise floor preventing detection of weak ones and significantly affecting dynamic range. In this article method of designing waveform with reduced no...

We demonstrate a high-performance optical arbitrary waveform shaper based on a single 10 GHz arrayed-waveguide grating with 64 loopback waveguides and integrated amplitude and phase modulators on each waveguide. The design is compact and self-aligning and allows for bidirectional operation. The device's complex transfer function is manipulated and measured over the full 640 GHz passband. To dem...

Next-generation communication systems are required to be efficient in power and spectrum usage. In this direction, novel spatial multiplexing techniques, such as orbital angular momentum (OAM), contrast frequency multiplexing, orthogonal division (OFDM), regarded uphold potential advantages. This letter investigates OAM OFDM along with their emerging variants index modulation (IM) MIMO configur...

1053-5888/09/$25.00©2009IEEE IEEE SIGNAL PROCESSING MAGAZINE [53] JANUARY 2009 W aveform-agile sensing is motivated by the improvements in performance that can result when the transmitted waveform is dynamically tailored to match the sensing objective and the environment. Waveform agility in active radar systems can provide performance improvements such as reduced target-tracking error, improve...
