The uniqueness of punctured binary sequence pairs is proposed and proved. In particular, perfect punctured binary sequence pairs (PPBSP), almost perfect punctured binary sequence pairs (APPBSP), pseudorandom punctured binary sequence pairs(PRBPSP) and punctured binary sequence pairs with two-level autocorrelation(PBSPT) are proved as the specific cases of perfect punctured LCZ/ZCZ sequence pairs....
In this paper, a novel frequency coded orthogonal IR-UWB (Impulse Radio UWB) pulse design method based on orthogonal carriers and ternary PN (Pseudo Noise) code is presented. The basic idea of the new approach is that the frequency-shifted sub-pulses are used to generate the orthogonal pulses by coding with PN sequence in frequency domain. Because the orthogonal carriers and PN codes are introduced...
In this paper, a novel frequency coded orthogonal UWB pulse design method based on orthogonal carriers and PN (pseudo noise) sequence is presented. The basic idea of the new approach is that the frequency-shifted sub-pulses are used to generate the orthogonal pulses by coding with PN sequence in frequency domain. Because the orthogonal carriers and PN codes are introduced into IR-UWB (impulse radio...
In this paper, a novel frequency-band coded orthogonal UWB pulse design method based on Chirp signal is presented. The new approach uses the chirp signals located at different frequency-bands to synthesize the orthogonal pulses by coding with Pseudo Noise sequence in frequency domain. The auto-correlation and cross-correlation property of the proposed chirp pulses are better than those of other conventional...
This paper proposes a completely new periodic correlation signal-almost perfect punctured binary sequence pair (APPBSP). We present the definitions of APPBSP and its transformation properties. To reduce the searching range and improve the searching efficiency of APPBSP, limited conditions of APPBSP are discussed to decide the punctured locations within the sequence pair. Searching results of APPBSP...
Considering the frequency spectrum characteristics of the UWB carrier envelope modulation (CEM) scheme which was first introduced in ("The carrier envelope modulation (CEM) scheme for ultra-wideband WPAN communication", IEEE ISCIT 2005, vol.2, pp.837-841, 12-14 Oct. 2005), a novel orthogonal comb spectrum correlation demodulation method is presented in this paper. In order to satisfy the...
