摘要

介绍了一种用于WCDMA/CDMA2000系统的二进制正交可变扩频因子(OVSF)、Hadamard和Walsh码生成的硬件单元。生成器使用扩展因子、模式选择和代码索引作为控制输入。合成硬件单元消耗512个nand2等效逻辑门。

Hardware unit for OVSF/Walsh/Hadamard code generation [3G mobile communication applications]

A hardware unit for producing binary orthogonal variable spreading factor (OVSF), Hadamard and Walsh codes for WCDMA/CDMA2000 systems is presented. The generator uses a spreading factor, mode select, and the code index as the control input. The synthesized hardware unit consumes 512 NAND2-equivalent logic gates.
