Abstract: PURPOSE: A single demodulator for soft-decision bit detection is provided to reduce complexity by calculating a soft decision value of each bit only using one time simple distance calculation of a received symbol and a predetermined hard decision boundary value. CONSTITUTION: A demodulator calculates an I(In phase) channel value corresponding to a horizontal axis value and a Q(Quadrature) channel value corresponding to a vertical axis value in a process of mapping a symbol about a received signal by constellation(300). The demodulator determines the I channel value and the Q channel value as an initial soft-decision bit value for first and second bits(400). The demodulator cyclically calculates the initial soft-decision bit value for third and more bits based on the initial soft-decision bit value for the first and second bits(500). The demodulator multiplies a gain to all initial soft-decision bit values calculated by a detection flow chart(600).

A feeding apparatus of a satellite communication multi-band antenna having a waveguide structure includes a common port(101), a straight line port(102), a side port(103), a connector(104), a partition(105), a coupling slot(106), and an iris(107). The common port of a circular waveguide shape passes a vertical/horizontal polarized wave signal of a Ku-band, and cuts off a vertical/horizontal polarized signal of an X-band. The straight line port of a spherical waveguide shape passes a vertical polarized signal of the Ku-band, and cuts off the horizontal polarized signal of the Ku-band. The side port passes the horizontal polarized signal of the Ku-band, and cuts off the vertical polarized signal of the Ku-band. The connector connects the common port to the straight line port. The partition cuts off the horizontal polarized signal of the Ku-band to be applied to the straight line port. The coupling slot couples the horizontal polarized signal of the Ku-band of the side port. The iris matches impedance between the coupling slot and the side port.
