摘要:针对基于软件无线电架构的现代移动通信手持终端设计,研究了基于SB3500国

产多核多线程数字信号处理器的软件无线电设计方法,实现了基于SB3500的软件无线电硬件系统。在此基础上开发了一套适合该硬件系统的OFDM通信波形软件,用于验证该硬件系统是否满足手持终端小型化和低功耗的要求。研究表明,使用该国产多核多线程处理器进行软件无线电系统的设计开发具有广泛的应用前景。

Abstract: For design of the contemporary mobile communication hand?held terminal, a design method of software defined radio (SDR) system based on domestic multi?core and

multi?threading digital signal processor SB3500 is studied. The SDR hardware system based on

SB3500 was implemented. An OFDM communication waveform software suitable for this hardware system was developed on the basis of this method to verify whether the hardware system can satisfy the miniaturization and low?power consumption requirements of the hand?held terminal. The research result shows this domestic multi?core and multi?threading processor for developing the SDR system has a good application prospect.
