LTE-based mobile satellite communication system is a combination of terrestrial LTE system and satellite communication techniques, which aims at improving the current LTE system's technical specifications for better service quality. AMC (Adaptive Modulation and Coding) technique is applied in current LTE system to improve system capacity and data(More)
In mobile satellite communication systems, Doppler shift is caused by the movement of both unified equipment and satellite, and differs from that in terrestrial mobile communication. Therefore, in OFDM based mobile satellite communication systems, the selection of sub-carrier bandwidth should be different. In this paper, the characteristic of Doppler shift(More)
Haploidentical haematopoietic stem cell transplantation (haplo-HSCT) used to be a third-line treatment option for childhood severe aplastic anaemia (SAA). We conducted this retrospective study of 36 children (38 transplants) who received haplo-HSCT from human leucocyte antigen (HLA)-mismatched related donors between July 2002 and November 2013 at five HSCT(More)

OBJECTIVE To investigate the combining therapy which not only have cured effect but also can uphold and improve the NPC patient's immunity function after radiotherapy and chemotherapy. METHOD 90 cases randomly divided into 3 groups 1. Local group (local injected with IL-2 + radiotherapy + chemotherapy); 2. General group (ivdrip with IL-2 + radiotherapy +(More)
By means of polyacrylaminde gel eletrothoresis and thin layer scanning, the paper semi-quantitatively studies some relation between component and activity of isoenayme of Ginseng infecting red skin desease. The results show activity of esterase increases 100% than that of normal Ginseng; activity of polyphenol oxidase increases 60-30% and represent new(More)
In polyethylene glycol-2000(PEG)-sodium sulfate (Na2SO4)-4-(2-Pyridylazo) resorcinol (PAR) system the extraction separation behaviour of the complexes of Pd(II), U(VI), Mo(VI) and La(III) was investigated. The results indicated that the complexes of Pd(II) and U(VI) with PAR were almost completely extracted by the PEG phase, La(III) was partly extracted,(More)
A three-layer interleaver scheme, which is added into TD-SCDMA specification for the compatibility with satellite environment, is proposed for 3G mobile satellite communication systems. Simulation results for satellite channel are presented, which demonstrate that the third interleaver can improve the system performance significantly and satisfy the(More)
