Abstract
A process for improving the reception quality of a Code Division Multiple Access (CDMA) signal that judiciously distributes reference symbols between two CDMA signal components, namely an in phase component (I) and quadrature component (Q). The reference symbols are distributed in only one of the two components, namely the I or Q component. To further improve the reception quality, the pseudo-random spreading sequence used for one of the components is different from the pseudo-random spreading sequence used for the other component. The applications of this process include mobile land radio communications.
