Center node: "binary compressive sensing via analog fountain coding"
  Abstract: In this paper, a compressive sensing (CS) approach is proposed for sparse binary signals' compression and reconstruction based on analog fountain codes (AFCs). In the proposed scheme, referred to as the analog fountain compressive sensing (AFCS), each measurement is generated from a linear combination of    $L$   randomly selected binary signal elements with real weight coefficients. The weight coefficients are chosen from a finite weight set and   $L$  , called measurement degree, is obtained based on a predefined degree distribution function. We propose a simple verification based reconstruction algorithm for the AFCS in the noiseless case. The proposed verification based decoder is analyzed through SUM-OR tree analytical approach and an optimization problem is formulated to find the optimum measurement degree to minimize the number of measurements required for the reconstruction of binary sparse signals. We show that in the AFCS, the number of required measurements is of   ${\cal O}(-n\log(1-k/n))$   , where   $n$   is the signal length and   $L=k$   is the signal sparsity level. Simulation results show that the AFCS can perfectly recover all non-zero elements of the sparse binary signal with a significantly reduced number of measurements, compared to the conventional binary CS and   $\ell_1$  -minimization approaches in a wide range of signal to noise ratios (SNRs) by using the standard message passing decoder. Finally, we show a practical application of the AFCS for the sparse event detection in wireless sensor networks (WSNs), where the sensors' readings can be treated as measurements from the CS point of view.
