Timing synchronization has been one of the largest challenges for Ultra-wideband (UWB) systems. To achieve the excellent performance, synchronization systems must have the characteristics of high speed, high accuracy and low complexity. In another literature, we have proposed a novel synchronization method, Multi-hypothesis Maximum Energy Path Acquisition (MH-MEPA) algorithm, based on the improved...
The paper proposes a new rapid synchronization method, i.e., multi-hypothesis maximum energy path acquisition (MH-MEPA) algorithm, with anti-timing jitter for ultra-wideband (UWB) systems in dense multipath environment. The method takes full advantages of the characteristics of the multi-hypothesis synchronization method and the indoor S-V channel propagation model proposed by IEEE 802.15.3a group...
The frame sync word (SW) is very important for burst data communication systems. The misdetection (including false alarm and detection failure) probability is a very good performance metric of a SW. Usually, the exact misdetection probability of one SW is obtained by Exhaustively Full Searching (EFS) through the whole error pattern space. EFS is straightforward, but the drawback is complexity. In...
Rapid synchronization acquisition is one of the biggest challenges of burst-mode transmission for ultra-wide band (UWB) wireless communications, especially for the impulse radio UWB (IR-UWB) due to the very short duration of the monopulse. Some rapid synchronization acquisition schemes have been proposed in the literature to reduce the mean acquisition time. However, most of them have no stability,...
The frame sync word (SW) is very important for burst data communication systems. Commonly used SWs such as m-sequences are not optimized for specific system environments in terms of misdetection (including false alarm and detection failure) probability. In this paper, both upper boundary and lower boundary of misdetection probability of frame synchronization are derived for given length and pattern...
Rapid synchronization acquisition plays a significant role in the structure design of ultra-wideband (UWB) receiver systems. We propose an improved rapid timing acquisition algorithm for UWB, bit reversal block search (BRBS), by employing a bit reversal technique in the serial block search (SBS) algorithm. The SBS algorithm does not provide the best choice of the search block length. Moreover, when...
