Original Abstract Submitted
a qam demodulator including a first calculation circuit including a real part returning circuit and an imaginary part returning circuit that derive, from a first complex symbol, an in phase (i) component and a quadrature phase (q) component, respectively; first and second comparators for receiving the i and q components, and based thereon, outputting respective bits of a bit string; first and second absolute value returning circuits that derive absolute values of the i and q components (“abs(i)”and “abs(q)”); first and second summers to sum each of abs(i) and abs(q) with a first reference value and thereby provide first and second summed outputs; and a sub-qam demodulator configured to qam demodulate a second complex symbol and thereby output corresponding bits. i and q components of the second complex symbol are based on the first and second summed outputs. the corresponding bits are remaining bits of the bit stream.
