A key challenge facing space-based computer vision systems is the presence of highly specular surfaces. Such surfaces present a challenge to conventional vision systems due to specular re ections, which may mask the true location of objects and lead to incorrect measurements. The problem is complicated by the fact that the use of high-powered illuminants, such as laser beams, can be problematic...

An edge-cancellation-aided iterative detection and decoding (EC-IDD) algorithm is proposed for polar-coded sparse code multiple access (SCMA), which jointly performs Gaussian-approximated message passing (GA-MP) of SCMA supported by the soft list (SLD) polar codes. A reduced-edge factor graph formulated in each consecutive iteration with aid cyclic redundancy check (CRC) EC. Based on simplified...

We propose a hybrid coded modulation scheme which composes of inner and outer codes. The outer-code can be any standard binary linear code with efficient soft decoding capability (e.g. low-density parity-check (LDPC) codes). is designed using deep neural network (DNN) takes the channel bits outputs modulated symbols. For training DNN, we to use loss function that inspired by generalized mutual ...
