    Abstract: A system, computer-readable storage medium and method of reflection seismic survey in a wireless seismic network within a survey area is described. The method includes detecting, in each of a plurality of wireless seismic sensor nodes, seismic reflection signals from a seismic energy source; recording, in each of a plurality of wireless geophones, detected seismic signals; transmitting, by the geophones, the recorded seismic signals as digital data, using a combination of Orthogonal Frequency-Division Multiple Access (OFDMA) and Time Division Multiple Access (TDMA), to a central data receiving device; changing the seismic energy source location for seismic reflection; and repeating the detecting, recording and transmitting a number of times for each change in seismic energy source.

    Abstract: A system, method, and non-transitory computer readable medium that perform blind signal estimation for single-input multiple-output systems. The method can include receiving, by the two or more receiver antennas of the receiver, an observed signal comprising the input signal and an additive noise term. The method can then form a data matrix using the observed signals from the two or more receiver antennas. The method can also include computing a singular value decomposition of the data matrix. The singular value decomposition can then be used to generate a parameter matrix. The method can then form a Toeplitz signal matrix using the parameter matrix. The method can estimating the input signal using the Toeplitz signal matrix.

    Abstract: An antenna is disclosed. The antenna includes a transparent substrate, a first square patch antenna element with a square lattice structure, a second square patch antenna element and a low profile transparent passive decoupling strip. The first square patch antenna element is disposed on the transparent substrate. The first square patch antenna element includes horizontal conductive wires and vertical conductive wires. The horizontal conductive wires and the vertical conductive wires cross each other and are equally spaced to form square spaces between. The second square patch antenna element is disposed on the transparent substrate. The second square patch antenna element has a structure identical to the structure of the first square patch antenna element. The first and the second square patch antenna elements are spaced apart from each other. The low profile transparent passive decoupling strip is disposed between the first and the second square patch antenna elements.
