In this paper, a code-shifted reference ultra-wideband (CSR-UWB) transceiver, which separates the reference pulse sequence and the data pulse sequences with a set of shifting and detection codes selected from Walsh codes, has been proposed to remove the ultra wideband delay element required by the transmitted reference UWB transceiver. As compared to the frequency-shifted reference UWB transceiver, which also can remove the delay element through separating the reference pulse sequence and the data pulse sequences with a group of analog carriers, the CSR-UWB transceiver has lower complexity as well as much better bit-error rate performance.
