Mathematically, the 1-bit CS model reads: $y = \\eta \\odot\\textrm{sign} (\\Psi x^* + \\epsilon)$, where $x^{*}\\in \\mathcal{R}^{n}, y\\in \\mathcal{R}^{m}$, $\\Psi \\in \\mathcal{R}^{m\\times n}$, and $\\epsilon$ is the random error before quantization and $\\eta\\in \\mathcal{R}^{n}$ is a random vector modeling the sign flips. Due to the presence of nonlinearity, noise and sign flips, it is quite challenging to decode from the 1-bit CS.
