In this paper,using cyclostationarity-based sensing method to detect the presence of Orthogonal Frequency Division Multiplexing(OFDM) signal over doubly-selecti
Deep space communications has played an important role in deep space exploration. Compared with common satellite and terrestrial communications, deep space comm
Nowadays, using Deterministic Finite Automata (DFA) or Non-deterministic Finite Automata (NFA) to parse regular expressions is the most popular way for Deep Pac
土壤CO_2释放是土壤碳转化的关键过程。氮(N)添加及植物枯落物的分解对湿地土壤CO_2释放速率有显著影响,在全球大气CO_2浓度和气候变化中具有重要作用。本研究选取闽江河口湿地土壤为研究对象,通过24 d的短期培养实验,研究不同氮浓度和不同枯落物添加对闽江河口湿地土壤CO_2释放速率的影响。结果表明:(1)短叶茳芏(Cyperus malaccensis)和互花米草(Spartina alter
