520 _ _ |a We have studied the time series of full disk integrated soft X-ray emission from the solar corona during January 2004 to December 2008, covering the entire descending phase of solar cycle 23 from a global point of view. We employ the daily X-ray index (DXI) derived from 1s cadence X-ray observations from the Si detector of ``Solar X-ray Spectrometer (SOXS)'' mission in four different energy bands ranging between $6 - 25~KeV$. The daily time series is subjected to power spectrum analysis after appropriate correction for noise. Lomb-Scargle periodogram technique has shown prominent periods of $ \sim13.5$ days, $ \sim 27$ days, and near Rieger period of $ \sim 181$ days and $ \sim 1.24$ years in all energy bands. Further to this, other periods like $ \sim 31$, $\sim 48$, $\sim 57$, $\sim 76$, $\sim 96$, $\sim 130$, $\sim 227$ and $\sim 303$ days are also detected in different energy bands. We discuss our results in the light of previous observations and existing numerical models.
