Wideband signal design for over-the-horizon radar in cochannel interference

Wideband signal design for over-the-horizon radar in cochannel interference

Ship detection in heavy sea clutter is a big challenge for over-the-horizon (OTH) radar. Wideband signal is helpful for improving range resolution and the signal-to-clutter ratio. In this paper, to support OTH radar employing wideband in cochannel interference, we propose environmental sensing-based waveform (ESBW) strategy, by considering transmit waveform design as an active approach and cogn...

Signal Design for Ultra-Wideband Radar and Wireless Communications

The emerging ultra-wideband technology is in demand of extensive theoretical as well as experimental research to advance the implementation and commercial use of its numerous applications. Impulse-type signals are characterized by an ultra-wide frequency bandwidth that is desirable for the applications of high-resolution radar and wireless communications. In this paper, a signal model referred ...

Triple Selection Diversity over Exponentially Correlated Nakagami-m Fading Channels Desired Signal and Cochannel Interference

In this paper, system performances of selection combining over correlated Nakagami-m channels are analyzed. Selection diversity based on the signal to interference ratio (SIR) is a very efficient technique that reduces fading and cochannel interference influence. Fading between the diversity branches and between interferers is correlated and Nakagami-m distributed with exponential correlation m...
