Micro-Doppler-Based Space Target Recognition with a One-Dimensional Parallel Network by Lixun Han, Cunqian Feng

“…Micromotion, as an inherent attribute of the target, can be used as the theoretical basis for target recognition. Meanwhile, time-varying micro-Doppler (m-D) frequency shifts induce frequency modulations on the target echo, which can be referred to as the m-D effect. m-D features are widely used in space target recognition as it can reflect the physical attributes of the space targets. …”

Measurement of event data from text by Patrick T. Brandt, Marcus Sianan

“…Three primary arguments are made: (1) It is important for users of event data to understand the measurement side of these data to avoid faulty inferences and make better decisions. (2) Avant-garde event data systems are still not free from some of the fundamental problems that plague legacy systems (investigated are theoretical and real-world examples of measurement issues, why they are problematic, how they are dealt with, and what is left to be desired even with newer systems). (3) One of the most crucial goals of event data science is to attain congruence between what is machine-coded/classified vs. the ground truth. …”

Low error floor LT coding algorithm by using fixed-length node classification window by Xin SONG, Naiping CHENG, Shuyan NI, Yurong LIAO, Tuofeng LEI

“…To solve the problem of high error floor for LT codes in additive white Gaussian noise (AWGN) channels, an improved coding scheme was designed.A fixed-length classification window was used to sort out the information nodes with relatively small degrees.Then these nodes would be forced to participate in the coding process frequently, so that they could obtain sufficiently high reliability.To design the optimal parameters, firstly, the bit error rate (BER) performance of LT codes and the cause of the error floor were analyzed, and the theoretical BER lower bound was introduced as the first constraint.Secondly, the extrinsic information gain loss ratio (GLR) was designed to measure the convergence behavior of the improved LT code, and maximizing the GLR was denoted as the second constraint.Finally, the influence of different parameters on algorithm efficiency and coding complexity were analyzed, and the principle of priority selection of parameters was pointed out as the third constraint.The simulation results show that compared with the conventional LT code, the proposed algorithm can reduce the error floor by nearly three orders of magnitude.Besides, the designed LT code outperforms the existing LT codes in literature in terms of bit error rate (BER) performance.…”
