OFDM通信系统高速ADC模块硬件实现

Design of high-speed ADC module in OFDM system

讨论了OFDM通讯系统高速ADC和DAC平台的硬件设计,对高速ADC、逻辑控制、高速缓存、高速DAC及DSP对I/O的同步读写进行了讨论和介绍,提出了更为有效的同步控制方式。利用CCS和示波器对数据进行了观察和分析。观察和分析结果表明,该系统能够有效地工作,验证了系统要求。

This paper has discussed the ADC and DAC hardware design. The high-speed ADC, control logic, FIFO and high-speed DAC were also discussed. Use CCS and oscilloscope to analyze the result. Then a more efficient synchronous control mode is proposed. These works achieve the requirement of the OFDM system.
