摘  要:
扩频通信作为第3代移动通信的核心技术,系统需要完成快速复杂的信号处理,对电路的处理速度提出了更高的要求。本文以直接序列扩频通信为对象,用软件Protel99SE设计了以FPGA芯片EP1C3T144C8N为核心的系统硬件电路,并将VHDL程序下载到硬件电路的EP1C3T144 C8N芯片中,得到了实际的较为满意的扩频信号波形,证明实现了扩频调制。实验结果表明本系统与传统的实现方式相比,系统的稳定性、可靠性和处理速度大大提高,减少了硬件延时,体现了FPGA的高速并行处理能力和全硬件实现的特点。

摘  要:
Spread Spectrum Communication as a third-generation mobile communications technology,the system needs to be done fast and complex signal processing,the circuit has set a higher processing speed.Based on direct sequence spread spectrum communications,targeting Protel99SE software designed to EP1C3T144C8N chip FPGA at the core of the system hardware circuit,the procedures VHDL and downloaded to the hardware circuit chip EP1C3T144 C8N,have been more satisfied with the actual spread spectrum signal Wave that has spread-spectrum modulation.The results show that the system with the traditional method,system stability,reliability and greatly increased processing speed and reduced hardware delay,reflecting the FPGA high-speed parallel processing hardware to achieve full capacity and features.
