Design scheme of a communication system based on software communication architecture( SCA) is intro-duced. System architecture, software and hardware platform and operation principle of the system are described. Characteristic of ad-hoc network is analyzed, development process of application waveforms and components of SCA-based ad-hoc network is presented. The ad-hoc network radio is based on GPP+DSP+FPGA hardware architecture, and modem hardware abstraction layer ( MAHL ) technique is utilized to realize the portability of waveforms on dedicated hardware processors. Different ad-hoc network protocols are implemented, therefore the radio is applicable to different circumstances.
