Orthogonal spread spectrum mobile internet transmission system having digital words and command elements coded following I and Q spread spectrum codes, each code set following phase rules |
摘要 |
<p>In-phase (I) and quadrature (Q) channels in a mobile unit are coded (13) producing digital word and command elements. Coded signals are passed to a code production unit, which forms spread spectrum codes attributable to the I and Q channels. The digital word elements, command elements and spread spectrum codes correspond to points in the same position and symmetrical with respect to a zero point on the phase domain. The elements are applied to a spread spectrum generator producing the signal modulation.</p> |
