In this paper, we study the power allocation and power splitting problem for simultaneous wireless information and power transfer (SWIPT) in a multi-user MISO broadcast system, in which there are two types of single-antenna users: traditional users that only receive information and modern users that receive information and energy simultaneously from a multi-antenna base station via power splitting...
In this paper, we comparative analysis the performance of DFT-based interpolation algorithm with different windows and Digital Lock-in amplifier(DLA) method. We recommend that DLA is a good choice for low signal to noise ratio (SNR). DFT-based interpolation can work with unknown frequency. In comparison with rectangle window, triangle window has better side-band affection with accuracy lose. Beside,...
Distributed compressed sensing (DCS), exploiting the correlation among multiple signals, enjoys the advantage of reduced number of measurements. This paper considers a type of joint sparsity model in DCS, where each signal contains a common component and an innovation component. In order to reduce the transmission cost, the measurements are derived as the sign information of the compressed samples...
