An ultra-wide bandwidth time-hopping spread-spectrum code division multiple-access system employing a binary PPM signaling has been introduced by . The Micropower Impulse Radar, James D. Taylor and Thomas E. McEwan Ultra-Wideband Technology for Intelligent Transportation Systems, Robert B. James and Jeffrey B. . Bounds and approximations are obtained for the average probability of error in an asynchronous slow-frequency-hopped spread-spectrum multiple-access communCited by: We consider a wireless Ultra-Wide Band (UWB) communication system using chirp spread spectrum (CSS) transmission technique. A system with high order modulation CSS technique is proposed. Our proposed system has inherited the advantages of CSS technique and common spread spectrum systems. It is immune to Doppler frequency offset and able to increase bit rate by the overlap technique.

Impulse radio, a form of ultra-wide bandwidth (UWB) spread-spectrum signaling, has properties that make it a viable candidate for short-range communications in dense multipath environments. Tan F. Wong: Spread Spectrum & CDMA 5. Code Acquisition and Tracking Chapter 5 Spreading Code Acquisition and Tracking No matter which form of spread spectrum technique we employ, we need to have the timing infor-mation of the transmitted signal in order to despread the received signal and demodulate the despread signal. Ultra Wideband Localization. As demonstrated by Krishnan et al. [3], Segura et al. [4], and Pivato et al. [5], ultra wideband communication differs from most other radio communication systems and has been used very effectively for robot mapping and localization. Instead of using a single frequency at any one time, a very broad range of. Ultra-wideband (also known as UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. UWB has traditional applications in non-cooperative radar recent applications target sensor data collection, precision locating and tracking .

The IGA is used to get accurate results for the low-duty DS systems. It is shown that lowering of chip-duty by keeping chip rate and chip length unchanged improves performance for asynchronous DS and both asynchronous and synchronous hybrid systems. However, under the same processing gain, a high-duty system performs better than a low-duty system.

A major advantage of spread-spectrum communication systems is their ability to exploit the multipath structure of the received signal. Different paths can be characterized by their time delays. Ultra-wideband (UWB) is an emerging technology for high speed short-range wireless communications. It has many attractive advantages such as high data rates, robustness to multipath fading and coexistence with narrowband wireless systems.
