A technique for orthogonal frequency division multiplexing frequency offset correction

HE TECHNIQUE described in this paper has been deT veloped to correct frequency offset errors in digital communications systems employing orthogonal frequency division multiplexing (OFDM) as the method of modulation. The aim of the paper is twofold; to show the effect offset errors have on the signal-to-noise ratio of the OFDM carriers and to present an algorithm to estimate offset so that it ma...

Correction and integration of normalized microarray data

drift correction technique

sensitivity of an electromagnetic type metal detector is directly related to stability, the higher the required sensitivity, the more frequently the rebalancing controls will have to be adjusted. thus, for maximum sensitivity in the head ,the use of automatic drift compensation network is necessary in order to cancel out the signal resulting from a slow drift in the coil system due to the tempe...

Normalized GNSS Interference Pattern Technique for Altimetry

It is well known that reflected signals from Global Navigation Satellite Systems (GNSS) can be used for altimetry applications, such as monitoring of water levels and determining snow height. Due to the interference of these reflected signals and the motion of satellites in space, the signal-to-noise ratio (SNR) measured at the receiver slowly oscillates. The oscillation rate is proportional to...
