这篇讲稿提出了一种新的方法,以显著低于奈奎斯特速率的速率捕获和表示可压缩信号。这种方法被称为压缩感知,它使用非自适应线性投影来保持信号的结构;然后使用优化过程从这些投影重建信号。
This lecture note presents a new method to capture and represent compressible signals at a rate significantly below the Nyquist rate. This method, called compressive sensing, employs nonadaptive linear projections that preserve the structure of the signal; the signal is then reconstructed from these projections using an optimization process.
