  Abstract

Noncoherent receivers are favored for block-code-modulated (BCM) ultrawideband impulse radio (UWB-IR) systems because of the relatively high performance and their low implementation complexity compared with coherent rake receivers. In the block coded modulation methods, the performance enhancement is obtained by using the orthogonality of codes to be multiplied to the pulses in a symbol. Therefore, a block is represented by the number of frame in a symbol and the frame time that is the time distance between pulses. As the frame/symbol duration is shortened to boost data rate, interframe interference (IFI) or intersymbol interference (ISI) occurs and degrades the detection performance of BCM. In this paper, we propose the time-overlapped template as a block-coded correlator. Proposed method results in the better performance compared to the conventional method, which is validated through the simulation and the analysis.
