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 hard-ware 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 pro-cessor for developing the SDR system has a good application prospect.
