软件无线电概念的引入使多模式信号的高速解调成为可能。当前数字信号处理器(DSP)的速度还无法满足大量数据的实时处理。描述了一种较好的软件化解调方案,给出了相应的算法,在相同的技术指标下,大大降低了所需计算量。针对该算法进一步给出了系统硬件实现框图。
The introduction of the software radio concept makes high-speed demodulation of multi-mode signals possible. Current digital signal processors (DSPs) are not fast enough to handle real-time processing of large amounts of data. Describes a better software demodulation scheme, gives the corresponding algorithm, with the same technical indicators, greatly reducing the amount of computation required. For the algorithm further gives the system hardware implementation diagram.
