Abstract:
1. A method of reducing data transmission loss after an occurrence of a transmit path failure in a wireless communication network, said wireless communication network comprising a base-station that comprises a Fourier transform matrix configuration, wherein the Fourier transform matrix configuration comprises at least one digital Fourier transform matrix and at least one analog Fourier transform matrix, said at least one digital Fourier transform matrix and said at least one analog Fourier transform matrix comprising a first, a second, and a third sector signal path and comprising a first, a second, and a third transmit path between said at least one digital Fourier transform matrix and said at least one analog Fourier Transform matrix, the signal paths each comprising first, second, and third gains, respectively, and first, second, and third phases respectively, the method comprising: detecting by a controller, a reduction in amplitude of a signal from a transmit path between a first digital Fourier transform matrix and a first analog Fourier transform matrix; reconfiguring, by the controller, the first digital Fourier transform matrix to a pass-thru mode by replacing usage of an input table with usage of a pass-thru table; and re-routing, by the controller, the first analog Fourier transform Matrix to a pass-thru mode; coupling an output of the first analog Fourier Transform matrix with an output of a second analog Fourier Transform matrix; and transmitting the coupled outputs.
