Performance analysis for pseudo-random asynchronous FH-CDMA system based on average-hit method

open access: yesDianxin kexue, 2016
The pseudo-random M-ary sequence (such as RS code,polynomial code and low-hit zone FH code and so forth) is widely adopted as FH code in FH-CDMA system.However,the performance of FH-CDMA system employing FH sequence is usually evaluated by simulation,and

Spatial distribution of scalar seismic moment release in Italy (1983-1996): seismotectonic implications for the Apennines

open access: yesAnnals of Geophysics, 1997
We analyzed the distribution of seismic moment in Italy, computed from instrumental seismicity recorded by the Italian National Seismic Network in the past 14 years, to map the areas where seismic deformation processes have been active in this time ...

Seismogenic zonation and seismic hazard estimates in a Southern Italy area (Northern Apulia) characterised by moderate seismicity rates [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2009
The northernmost part of Apulia, in Southern Italy, is an emerged portion of the Adriatic plate, which in past centuries was hit by at least three disastrous earthquakes and at present is occasionally affected by seismic events of moderate energy. In the
