Abstract  Abstract

The present application discloses an improved mobile communications architecture in which each base station broadcasts not only data which has been spread by that stations long code word but also (intermittently) code identification data which has not been spread. The code identification data is a block code which includes multiple symbols so that multiple intermittent transmissions are required to complete the transmission of the code identification data. This transmission lets the mobile station shorten the search for the base stations long code word in two ways: the code identification data gives at least some information about the long code itself; and the phase of the block code gives at least some information about the phase of the long code word.
