Matching real/complex nature of modulation scheme, pilot signal and scrambling code to improve interference rejection capability calculations

摘要

The claims specify relating the choice of pilot symbol and scrambling code to the choice of modulation scheme, probably in the context of an adaptive modulation and coding system. Dependent claims then limit one or more of the three elements to be either real valued or complex valued. The description discusses interference in cellular systems and proposes limiting transmission to all real values in some situations to simply interference covariance calculations used in interference rejection systems.
