Abstract

Food integrity is a major global public issue. China's food industry has demonstrated a sustained growth trend since the 1980s; however, the years between 1980 and 2012 witnessed a worrisome food integrity situation. Thankfully, in recent years, the situation is improving after the Chinese government's implementation of food safety regulations. In order to understand the current status of food integrity in China, this study analyzes the national food spot check data in 2016. The data covers almost all kinds of food in the market, and it reveals that overuse of food additives, microbial contamination and subpar food quality indicators are the top three factors limiting food integrity. Additionally, the paper discusses other challenges that affect food integrity in China, and we make suggestions for improving food integrity.

Abstract

Sparse code multiple access (SCMA) is a competitive nonorthogonal access scheme for the next mobile communication. As a multiuser sharing system, SCMA adopts message passing algorithm (MPA) for decoding scheme in receiver, but its iterative method leads to high computational complexity. Therefore, a serial message passing algorithm based on variable node (VMPA) is proposed in this paper. Making some subtle alterations to message update in original MPA, VMPA can greatly reduce overall computing complexity of decoding scheme. Furthermore, considering that serial structure may increase decoding delay, a novel grouping scheme based sparse matrix is applied to VMPA. Simulation results verify that the new algorithm, termed as grouping VMPA (G-VMPA), can achieve a better tradeoff between bit error rate (BER) and computing complexity than MPA.
