Abstract	Ultra-wideband communications synchronization is a challenging work because of its ultra short pulse shape and the ultra dense multi-path interference. This paper proposes a simple scheme using pilot codes as transmitted reference (TR) to assist the frame and bit acquisition. A new architecture, the reference aided matched filter (RAMF), is presented in this paper. This method avoids complex Rake fingers to estimate channel parameters and high sampling rate for interpolation. To optimize performance, an adaptive post detection integration (APDI) is well designed to capture as much energy as possible for acquisition. In addition, a low complexity early-late gate tracking loop is embedded in both tracking and acquisition functions. The sampling rate for the receiver is at symbol speed for practical implementation of a simple digital receiver
