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).
