A comparison of frequency offset estimation methods in Orthogonal Frequency Division Multiplexing (OFDM) systems
(Monterey California. Naval Postgraduate School, 2004-12)
OFDM is a modulation technique that achieves high data rates, increased bandwidth efficiency and robustness in multipath environments. However, OFDM has some disadvantages, such as sensitivity to channel fading, large peak ...
Reed-Muller codes in error correction in wireless adhoc networks
(Monterey California. Naval Postgraduate School, 2004-03)
The IEEE 802.11a standard uses a coded orthogonal frequency division multi-plexing (COFDM) scheme in the 5-GHz band to support data rates up to 54 Mbps. The COFDM was chosen because of its robustness to multipath fading ...
Design of microstrip patch antenna for the NPSAT1
(Monterey, Calif. Naval Postgraduate School, 2002-12)
This thesis presents the design of two circularly polarized patch antennas for operation at 1.767 GHz and at 2.207 GHz (for receiving and transmitting, respectively) on NPSAT1 satellite. The design requirements for the ...
The minimization of multiple valued logic expressions using parallel processors
(Monterey, California. Naval Postgraduate School, 1991-09)
The process of finding an exact minimization for a multiple-valued logic (MVL) expression requires an extensive search and enormous computation time. One of the heuristics to reduce this computation time is the Neighborhood ...
The path prediction of cyclones with Kalman filters
(Monterey, California: Naval Postgraduate School, 1990-09)
The Kalman filter is used to provide estimates of the position and velocity of a storm based upon observation of the storm's longitude and latitude. Nonstationary noise is shown to degrade the performance of the filter and ...
Application of the constrained implicants set concept to the minimization of binary functions
(Monterey, California. Naval Postgraduate School, 1990)
Several heuristics and algorithms have been developed to find minimal sum-of-products expressions in binary logic. Most of them use prime implicants during minimization process. An efficient search strategy has been developed ...
This thesis estimates the frequency response of a network where the only data is the output obtained from an Autoregressive-moving average (ARMA) model driven by a random input. Models of random processes and existing ...
