In this paper, a novel type of transceiver for impulse radio ultra-wideband systems, the code-shifted reference transceiver, has been proposed to remove the delay element with an ultra wide bandwidth required by the transmitted reference transceiver. As compared to the frequency-shifted reference transceiver that removes the delay element through separating the reference and data pulse sequences with a group of analog carriers, the code-shifted reference transceiver separates the reference and data pulse sequences with a set of shifting and detection codes selected from Walsh codes. Therefore, the performance evaluations obtained from both theoretical analysis and computer simulations show that in conjunction with a much lower system complexity, the code-shifted reference transceiver can achieve a much better bit-to-error rate performance than the frequency-shifted reference transceiver can.
