Abstract
This paper presents an overview of codes used in CDMA systems. It briefly reviews theoretical aspects of pseudo-noise sequences as well as orthogonal spreading codes for CDMA cellular systems, focusing on both scrambling and channelization code generation suitable for 3GPP FDD UMTS. For each code generator, we point out architectural aspects as well as implementation issues. |
