'''Multiplexed binary offset carrier''' (MBOC) modulation <ref>SIS-ICD08</ref><ref>NaviJournal08</ref> is a modulation proposed for Galileo <ref>SIS-ICD08</ref> and modernized GPS signals, which combines a sine [[binary offset carrier]] SinBOC(1,1) signal with a SinBOC(6,1) signal, either via weighted sum/difference (the CBOC implementation) or via time-multiplexing (the TMBOC implementation). Its [[power spectral density]] <math>\Phi(f)</math> is defined via <ref>Agreement06</ref>

The main objective of the common GPS and Galileo signal design activity was that the power spectral density (PSD) of the proposed solution would be identical for GPS L1C and Galileo E1 OS when the pilot and data components are computed together<ref>[http://www.navipedia.org/index.php/MBOC_Modulation Navipedia information on MBCO Modulation]</ref>. This assures high interoperability between both signals. Its [[power spectral density]] <math>\Phi(f)</math> is defined via <ref>Agreement06</ref>

<math>\Phi(f)=\frac{10}{11}BOC(1,1)+\frac{1}{11}BOC(6,1)</math>
