&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Multiplexed binary offset carrier&amp;#039;&amp;#039;&amp;#039; (MBOC) modulation &amp;lt;ref&amp;gt;SIS-ICD08&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;NaviJournal08&amp;lt;/ref&amp;gt; is a modulation proposed for Galileo &amp;lt;ref&amp;gt;SIS-ICD08&amp;lt;/ref&amp;gt; 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]] &amp;lt;math&amp;gt;\Phi(f)&amp;lt;/math&amp;gt; is defined via &amp;lt;ref&amp;gt;Agreement06&amp;lt;/ref&amp;gt;&lt;br /&gt;
&amp;lt;math&amp;gt;\Phi(f)=\frac{10}{11}BOC(1,1)+\frac{1}{11}BOC(6,1)&amp;lt;/math&amp;gt;&lt;br /&gt;
