Abstract :
One of the biggest challenges in ultra-wideband impulse radio (UWB-IR) is timing acquisition. To accomplish synchronization, a novel modulation scheme is presented in this paper. Relying on the unique signal structure and the first order- statistics of the received signal, the timing offset can be acquired by energy detection even if in the presence of inter-frame interference (IFI) and inter-symbol interference (ISI). Simulations and comparisons confirm that the proposed approach outperforms the existing similar one in term of normalized mean square error (MSE) and bit error rate (BER).
