Background and Purpose
Epidemiological and experimental studies suggest that microbial exposure in early childhood is linked with reduced risk to suffer asthma. Thus microbial components with immunoregulatory capabilities might serve as a preventive strategy for allergic asthma. Recently, it was identified that Streptococcus pneumoniae aminopeptidase N (PepN) could suppress T cell effector function...
In this paper, a robust frequency synchronization scheme is proposed for joint estimation of carrier frequency offset (CFO) and sampling frequency offset (SFO) in orthogonal frequency division multiplexing (OFDM) systems. CFO and SFO are simultaneously analyzed in the OFDM system, in which carrier and sampling frequency are generated in a common crystal oscillator. The estimation algorithm is based...
