These WFs are based on the use of sine-phased binary offset carrier (BOC) with adjustable width (BOC-AW). They are generated by adjusting the width of the three-level WF {-1, 0, 1}. By exploiting the three-level BOC-AW subcarriers in sine-phasing signal model, we developed several forms of BOC-AW by means of superposition and width adjustment. The resulting power spectral densities and autocorrelation functions of the proposed WFs were calculated and introduced. Also calculated were the spectral separation coefficients (SSCs) and the Cram\u00e9r-Rao lower bounds (CRLBs). The SSCs and CRLBs prove the efficiency of the proposed WFs in terms of interference separation. In addition, the simulation results show that the proposed WFs present better performances in MP mitigation compared to the WFs adopted by the Galileo and global positioning system modernization.<\/jats:p>","DOI":"10.1186\/1687-1499-2013-124","type":"journal-article","created":{"date-parts":[[2013,5,9]],"date-time":"2013-05-09T16:14:20Z","timestamp":1368116060000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Performance of new BOC-AW-modulated signals for GNSS system"],"prefix":"10.1186","volume":"2013","author":[{"given":"Mustapha","family":"Flissi","sequence":"first","affiliation":[]},{"given":"Khaled","family":"Rouabah","sequence":"additional","affiliation":[]},{"given":"Djamel","family":"Chikouche","sequence":"additional","affiliation":[]},{"given":"Abdehalim","family":"Mayouf","sequence":"additional","affiliation":[]},{"given":"Salim","family":"Atia","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2013,5,9]]},"reference":[{"key":"683_CR1","unstructured":"Betz JW: The offset carrier modulation for GPS modernization.
