    • Systems and methods in accordance with embodiments of the invention utilize a CS architecture based on a sub-linear time recovery process (with reduced memory requirements). In several embodiments, a novel structured measurement matrix is exploited during signal acquisition allowing the use of a recovery process based on relatively simple computational primitives making it more amenable to implementation in a fully-integrated form. One embodiment of the invention includes an analog front end configured to receive an analog input signal, and CS sampling circuitry connected to an output of the analog front end and configured to generate a plurality of measurements using a structured measurement matrix, where each row of the structured measurement matrix is generated using a different predetermined check node. In addition, the CS sampling circuitry is configured to generate the plurality of measurements at a rate that is less than the Nyquist rate of the analog input signal.
    • 根据本发明的实施例的系统和方法利用基于亚线性时间恢复过程(具有减少的存储器要求)的CS架构。 在几个实施例中,在信号获取期间利用新颖的结构化测量矩阵,允许使用基于相对简单的计算原语的恢复过程,使得更适合以完全集成的形式实现。 本发明的一个实施例包括被配置为接收模拟输入信号的模拟前端和连接到模拟前端的输出并被配置为使用结构化测量矩阵生成多个测量的CS采样电路,其中, 使用不同的预定校验节点生成结构化测量矩阵。 此外,CS采样电路被配置为以小于模拟输入信号的奈奎斯特速率的速率产生多个测量。
