Constant Amplitude Modulation for Wireless Channels at 60 GHz
, 2001
"... The aim of this thesis was to simulate the performance of an equalized Gaussian Minimum Shift Keying (GMSK) signal for indoor applications at 60 GHz frequency band, with noise and Intersymbol interference (ISI). A Decision Feedback Equalizer (DFE) was designed to cope with the ISI and noise. The sys ..."

A Constant Amplitude Multiplexing for MultiCode DS/CDMA Systems
"... Abstract—In general, the signal of the conventional multicode CDMA system has large fluctuations, and these fluctuations increase nonlinear distortion at a high efficient nonlinear amplifier. To reduce nonlinear distortion, the amplitude fluctuations of the signal should be reduced as much as possi ..."

as possible, so majority multiplexing and constant amplitude coding are developed. But, as the system uses more codes, both methods make the system more complex, because the data bits are coded several times. The proposed system does not need the additional coding and just needs simple sign operations

nsients is approximately 1000 volts. For a system delivering a sinewave into a nonresonant kicker, a 10 kW amplifier would be required. The power available in the present system * This work was supported by the National Science Foundation CBN 9816 18 August 1998 2 with a linear amplifier is only 400 watts (140 volts peak) and is obtained by combining the outputs of a pair of 200 watt commercial broadband power amplifiers. In the linear feedback system these 200 watt amplifiers drive a 50 ohm stripline kicker which is shorted at one end [1]. The plates of the kicker are powered differentially using a hybrid power divider driven by the combined amplifier output. Horizontal excitation is produced directly through deflection of the beam at the kicker. Longitudinal or energy excitation also uses deflection and requires dispersion at the kicker so that horizontal deflections translate into acceleration by changing the orbital path length [2]. Since the kicker is
Robust Uncertainty Principles: Exact Signal Reconstruction From Highly Incomplete Frequency Information
