摘要

提出了一种软件定义收发器的设计方案:设计并制作了一种低功耗数字基带处理器(DBP)。DBP的调制器和信道编码参数可以在不同场景下重新配置。提出了一种基于商用现货无线电平台的软件定义收发器设计流程。在该平台上提出并实现了与DBP配对的可编程收发器，使其能够与不同的高层协议接口。仿真结果表明，在840 kbps的工作负载下，DBP功耗为92.8 μ W$，在信噪比为15 dB时，可编程收发器的误码率为10^{-4}$。所提出的收发器已在台架测试中得到验证。

Design of a Software-Defined Transceiver with High Flexibility for Sensing Applications

This paper proposed a design of software-defined transceiver: A low-power digital baseband processor (DBP) was designed and fabricated in $40 nm$ CMOS process. The modulator and channel coding parameters of the DBP can be re-configured while the proposed design is used in different scenarios. A design flow of software-defined transceivers based on a COTS (Commercial Off-the-Shelf) radio platform was proposed. A programmable transceiver paired with the DBP was proposed and implemented on this platform, enabling the ability to interface with different higher layer protocols. Simulation results show that the DBP consumes $92.8 \mu W$ power in a work load of 840 kbps, and the programmable transceiver can achieve a bit error rate of $10^{-4}$ at the signal to noise ratio of 15 dB. The proposed transceiver has been verified in the bench test.
