Today, body and personal area network sensors are becoming ubiquitous in applications such as fitness and health, environmental sensing and military. For such applications, the design of communication systems that have very low-power consumption and provide flexible and robust data transmission is a highly marketable solution. While conventional transceivers have been introduced for low-power operation, they are not as well-suited to duty cycling as impulse-radio ultra-wideband (IR-UWB) systems which can operate during very narrow time frames. Moreover, IR transceivers are much simpler, and can potentially offer very high transmission efficiency. Many standards for low-power communication exist, and allow considerable flexibility on channel availability and data rates such that under different communication links, different modulation schemes and transmitted spectrum shapes may be optimal. Transceivers that can not only vary their pulse modulation, but also dynamically adjust their transmission frequency and bandwidth are thus highly desirable as they allow for robust communication in various environments and can attain the best data rate, spectrum shape and power consumption compromise.

如今，身体和个人区域网络传感器在健身和健康，环境传感和军事等应用中变得无处不在。对于此类应用，具有非常低功率并提供灵活且可靠的数据传输的通信系统的设计是一个高度可销售的解决方案。尽管已经引入了用于低功率运行的常规收发器，但它们并不像Impulse-Radio Ultra-Wideband（IR-UWB）系统那样非常适合税收骑行，该系统可以在狭窄的时间范围内运行。此外，红外收发器要简单得多，并且可能具有很高的传输效率。存在许多低功率通信的标准，并允许在通道的可用性和数据速率上具有相当大的灵活性，以便在不同的通信链接，不同的调制方案和传输频谱形状可能是最佳的。因此，收发器不仅可以改变其脉冲调制，而且还可以动态调整其传输频率和带宽，因此非常需要，因为它们允许在各种环境中进行稳健的通信，并且可以达到最佳数据速率，频谱形状和功耗损害。
