Orthogonal code generator for 3G wireless transceivers
Boris D. Andreev, E.L. Titlebaum, Eby G. Friedman · 2003
Orthogonal variable spreading factor (OVSF) codes are standard in third generation UMTS cellular systems. The efficient generation of these codes is essential for reducing the area and power of wireless transceivers. In this paper, the basic properties of this family of codes are analyzed from an RTL perspective and two efficient hardware code generators are proposed. Tradeoffs and design solutions as well as low power considerations are discussed. These results represent the first reported implementation of an OVSF code generator.
