Non-data aided EM-Based channel estimation for OFDM systems with time-varying fading channels
(Kluwer Academic Publishers, 2002)
In this paper, a computationally efficient algorithm is presented for maximum a posteriori (MAP) channel estimation for OFDM systems employing M-PSK modulation scheme with additive Gaussian noise, based on the Expectation ...
P-T phase diagram for NH?F
(Editions Scientifiques Medicales Elsevier, 2002-04)
In this study we obtain a P-T phase diagram of NH4F using the mean-field theory. We fit our calculated phase line equations to the experimental P-T phase diagram. By choosing appropriately the coefficients in the free-energy ...
T-P phase diagram of ammonia solid phases I, II and III
(Elsevier Science, 2002-01-02)
In this study, using the mean field theory, we obtain temperature versus pressure phase diagram for the liquid and solid phases I, II, and III of ammonia. We fit, our phase line equations to the experimentally observed ...

Maximum a posteriori multipath fading channel estimation for OFDM systems
(Assoc Elettrotecnica Ed Elettronica Italiana, 2002-10)
In this paper, a non-data-aided maximum a posteriori (MAP) channel estimation technique for OFDM systems employing M-PSK modulation scheme is proposed. The technique requires a convenient representation of the discrete ...
Monitoring diffusion of reptating polymer chains by a direct energy transfer method: A Monte Carlo simulation
(Wiley-Blackwell, 2002-07-29)
A kinetic Monte Carlo method was used to simulate the diffusion of reptating polymer chains across an interface. A time-resolved fluorescence technique in conjunction with a direct energy transfer method was used to measure ...

(Physical Soc Japan, 2002-08)
Contribution of higher order terms in the perturbation expansion for the strongly dispersive ion-plasma waves is examined through the use of modified reductive perturbation method developed by us [J. Phys. Soc. Jpn. 68 ...
Complex and real rays in three dimensional Minkowski space
(IEEE, 2002)
A new approach to the theory of complex rays is proposed. It is shown that the Minkowski space is more appropriate for describing these rays than the usual, Euclidian spaces. Some illustrative examples are represented.
Channel estimation for space-time block coded OFDM systems in the presence of multipath fading
