基于声卡的软件调制解调技术的研究

Study on the technology of soft-modulation and soft-demodulation based on sonic card

用软件来实现信号的调制与解调是当前通信领域中的先进技术之一,基于软件无线电的思想,研究了一种以多媒体计算机声卡为基本硬件平台的软件调制解调技术。给出了系统整体方案和详细软件流程图,并通过了实际验证能够实现。

It is one of the most advanced technologies in the current communication field that realizing modulation and demodulation by software. This paper studied the technology of soft - modulation and soft - demodulation taking sonic card of the computer as basic hardware platform on the basis of the thought of the software radio. The system solutions and software flow chart are given and they are proved realizable.
