Ultra wideband communication is a promising technology with attractive features of low power, low complexity transceiver and rich multipath diversity that can be used for transmitting both high and low data rates. Exploiting the inherent capabilities of UWB communication is up to perfect synchronization between transmitter and the receiver which is a serious bottleneck of these systems. Using very...
Focusing on the packet acquisition of UWB non-coherent system, a novel scheme is proposed in this article, which combines frame synchronization with signal acquisition and bit error probability (BEP) optimization together. Online signal to noise ratio (SNR) estimation is made for minimize BEP function after signal acquisition, combined with the search of optimal length of integral window. Experiments...
In this paper, the optimal energy detection receivers for on-off keying (OOK) in ultra-wideband impulse radio (UWB-IR) systems are discussed.We discuss three schemes of optimizing receivers, the first one optimizes the integration interval, the second one optimizes the energy threshold value, and the last one is the scheme of combination of these two schemes. Their characteristics are evaluated by...
