    • Methods, devices and systems for sensor-based wireless communication systems using compressive sampling are provided. In one embodiment, the method for sampling signals comprises receiving, over a wireless channel, a user equipment transmission based on an S- sparse combination of a set of vectors; down converting and discretizing the received transmission to create a discretized signal; correlating the discretized signal with a set of sense waveforms to create a set of samples, wherein a total number of samples in the set is equal to a total number of sense waveforms in the set, wherein the set of sense waveforms does not match the set of vectors, and wherein the total number of sense waveforms in the set of sense waveforms is fewer than a total number of vectors in the set of vectors; and transmitting at least one sample of the set of samples to a remote central processor.
    • 提供了使用压缩采样的基于传感器的无线通信系统的方法,设备和系统。 在一个实施例中,用于采样信号的方法包括:通过无线信道,基于一组向量的S-稀疏组合来接收用户设备传输; 下转换和离散接收的传输以产生离散化信号; 将离散化信号与一组感测波形相关联以产生一组采样,其中该组中的采样的总数等于该组中的感测波形的总数,其中该组感测波形与该组不匹配 并且其中所述组的检测波形中的检测波形的总数少于所述一组向量中的矢量的总数; 以及将所述一组采样的至少一个样本发射到远程中央处理器。
