Giuliano. Space Telescope Science Institute. What I do. I work for the Space Telescope Science Institute (STSCI) which is responsible for operating the Hubble Space Telescope. STScI. is responsible for all phases of science operations including:. Division Multiplexing CO-OFDM. 1. Principle of orthogonal frequency-division multiplexing (OFDM). The principles of orthogonal frequency division multiplexing (OFDM) modulation have been in existence for several decades. However, in recent years these techniques have quickly moved out of textbooks and research laboratories and into practice in modern communications systems. The techniques are employed in data delivery systems over the phone line, digital radio and television, and wireless networking systems. Overview. Frequency Metrology. Measuring Frequency Gaps.

Berta (Harvard), the P.I. of HST program 12251, “The first characterization of a Super-Earth Atmosphere,” graciously agreed to our request to use GJ 1214 also for our engineering test, program 12325. Many persons, especially Merle Reinhart, Alan Welty, and William “Bill” Januszewski (STScI) helped plan the observations. Art Bradley (SSES) and Mike Wenz (GSFC) provided FGS data and analysis. .
