Phase-Shifting Multi-Wavelength Dynamic Interferometer

The benefits of using two-wavelength measurements to extend the dynamic range of an interferometric measurement are well known. We present a new multi-wavelength interferometer that uses two successive single frame measurements obtained rapidly in time to significantly reduce sensitivity to vibration. At each wavelength, four phase-shifted interferograms are captured in a single image. The tota...

Multi-Carrier CDMA in Rayleigh Fading Channel

Abstract: The application of Wiener filtering to the detection of Multi-Carrier Code Division Mult iple Access (MC-CDMA) signals is analyzed. An analytical model is developed to evaluate an MCCDMA system with a very large number of subcarriers. This model is compared with simulations for 8 and 64 subcarriers. Simulation results are also presented on the effect of correlated fading (in the frequ...

Design of Compact Multi-Channel Diplexer Using Defected Microstrip Structure

In this paper, two compact quad-channel and six-channel diplexer are designed and fabricated using defected microstrip structure (DMS). This structure is designed for the desired frequency based on the literature reviews. The proposed configuration is composed of a conventional T-junction divider with two pairs of open bended stubs and dual/tri-band filters. In designing dual band filters, a lo...

Calibration methods for a multi-channel multi-frequency EIT system.

Multi-channel multi-frequency electrical impedance tomography (EIT) systems require a careful calibration to minimize systematic errors. We describe novel calibration methods for the recently developed KHU Mark1 EIT system. Current source calibration includes maximization of output resistance and minimization of output capacitance using multiple generalized impedance converters. Phase and gain ...

Multi-Carrier DS-CDMA Using Frequency Spread Coding

In this paper, a type of multi-carrier direct sequence code division multiple access (MC-DS-CDMA) system which uses frequency spread coding is proposed and investigated for the down-link. An MC-DS-CDMA system is a combined system of CDMA and multi-carrier modulation. This system is often categorized as a “serial to parallel (S/P) type” system because serial to parallel converted data symbols ar...
