    • A frequency band, to be used by each cell within a group of cells, is obtained and the number, m=2 n (n=1, 2...), of orthogonal sub-carriers, f 1 , f 2 , .., f m , over which individual data are transmitted in each communication channel, is determined for all cells within the group. A phase, φ i , is allocated to each sub-carrier f i (I=1,2,..,m) within a cell, such that the absolute value φ i is determined by the data that is transmitted, and by the digital modulation scheme, and is identical for all f i within the cell, and the sign of each φ i within the cell is identical to the sign of a corresponding element taken from a row in an mxm Walsh-Hadamard matrix that corresponds to that cell, such that neighbouring/overlapping cells use different rows. The data in each cell are transmitted over the sub-carriers with their corresponding phases. All transmissions carried by all sub-carriers are received and the total phase Φ i of all the received signals at frequency f i is obtained. The sign of total phase Φ i is changed for each cell, for all values of i that correspond to negative elements in the corresponding row of that cell's matrix. The phase, φ i , of any transmitted sub-carrier, f i , is obtained by summing the values of the total phase, Φ i , after changing phase signs, and dividing the result of the summation by a number determined according to m and/or the ratio between the magnitudes of the sub-carriers within a cell, and the magnitudes of the sub-carriers within its neighbouring/overlapping cells.

    • Abstract A single-wire electric transmission line system that includes a power sources having first and second poles and a phase shifting device, coupled to one of the poles of the power source, in such a manner that the phase shifting device shifts the phase of a first signal propagating through the pole such that the shifted phase of the first signal will be essentially identical to the phase of a second signal propagating through the other pole. The shifted first signal is added to the second signal with essentially the same phase of second signal, whenever both poles are connected together to form a single-wire, through which the resulting added signal propagates

    • The present invention is directed to a method for canceling the Doppler shift, multi-path propagation, delays, and long time selective fading influences of phase and/or amplitude modulated signals carried by RF sub-carriers, without requiring pilot signals. The number of m=2 n , over which individual datum is transmitted in each communication channel, is determined. Pairs of Walsh functions are selected from a Walsh-Hadamard matrix such that each function is not selected more than once. Each signal is partitioned to its I factor and Q factor and coding each I and Q factors of the signals by the pair functions. A corresponding phase and amplitude is allocated for each sub-carrier wherein the amplitude and phase values are determined by the data that is transmitted, the digital modulation scheme or inverse spectral transformation, and signs of both corresponding elements taken from the pair Walsh functions. Data is transmitted over the sub-carriers and received and the corresponding phases and amplitudes of all the received signals are obtained using spectral transformation. The received signals are decoded by changing signs of I and Q factors of the received signals in accordance with corresponding elements from the pair functions, used to decode said signals. The I and Q factors of received signals are summed separately, after changing signs of said I and Q factors of received signals, and each of the summations of I and Q factors is divided by m. The signal is reconstructed using said divided I and Q factors, by calculating its phase.

    • Method and system for increasing the number of communication channels that can be simultaneously established within a cell being part of a group of cells. A frequency band to be used by each cell within the group is obtained and the number of m = 2n ( n =1, 2...,) identical orthogonal sub-carriers f1, f2, fm , over which individual data is transmitted in each communication channel is determined for all cells within the group. A corresponding phase φ i is allocated for each sub-carrier fi ( i =1, 2,..., m ) within a cell, such that the absolute value |φ i | is determined by the data that is transmitted and the digital modulation scheme, and is identical for all f i within the cell, and the sign of each φ i within the cell is identical to the sign of a corresponding element taken from a row in a mxm Walsh-Hadamard matrix that corresponds tothe cell, such that neighboring/overlapping cells use different rows. The data in each cell is transmitted over the sub-carriers and their corresponding phases. All transmissions carried by all sub-carriers are received and the total phase φ i of all the received signals at frequency fi is obtained. The sign of total phase φ i is changed for each cell for all i values that correspond to negative elements in the corresponding row of the cell. The phase φ i , of any transmitted sub-carrier fi , is obtained by summing the values of the total phase φ i , after changing phase signs, and dividing the result of the summation by a number determined according to m and/or the ratio between the magnitudes of the sub-carriers within a cell, and the magnitudes of the sub-carriers within its neighboring/overlapping cells.
