JTRS正致力于将可互换SDR(软件无线电)带入军用领域。但SDR对商业应用是否也是足够好的选择呢?SDR(软件无线电)并不是一种新技术。过去业界就已经尝试实现SDR,但都没有达到目标。最近激发起对SDR兴趣的是创新性软硬件技术的出现,这些技术能够以市场可承受的价格提供足够的灵活性、性能和功率效率。例如,宽带变换器现在可以工作在宽频率范围内,根据一种特定的位分辨率处理接收到的波形,而高频处理器可以直接与信号工作,从而省掉IF(中频)级,并降低成本。
JTRS is working to bring interchangeable SDR (software radio) to the military. But is SDR a good enough choice for business applications? SDR (Software Defined Radio) is not a new technology. In the past, the industry has tried to achieve SDR, but did not achieve the goal. Recent developments that have inspired SDR are the emergence of innovative hardware and software technologies that provide sufficient flexibility, performance, and power efficiency at affordable prices. For example, broadband converters can now operate over a wide frequency range, process received waveforms based on a particular bit resolution, and high-frequency processors can work directly with signals, eliminating the need for IF levels and reducing cost.
