一种宽带CDMA芯片的设计与实现

A new design and implementation of the wideband CDMA ASIC chip

提出了一种宽带ＣＤＭＡ芯片的设计方案，该方案采用了并行数字相关技术，并用ＥＰＬＤ器件实现了该方案．实现芯片的伪码速率为６．４Ｍｃｈｉｐ／ｓ，信息速率为１Ｍｂｉｔ／ｓ，文中还给出了对该芯片的测试结果．

This paper proposes a new design scheme for wideband CDMA ASIC chips, based on temed spread spectrum and parallel digital correlation processing. The chip is implemented by EPLD technology with the PN code chip rate of 6.4 Mchip/s and data rate of 1 Mbit/s . The test result shows that our design purpose is achieved and the chip satisfies the wireless LAN application environment.
