Abstract (en)
[origin: WO9845970A1] A system transmits digital information bits, which are encoded into a predefined number of signed symbols per frame from a transmitter (40) over a network (46) to a receiver, wherein the transmitted signed symbols have a desired spectral shape; the digital information bits being divided into a first predetermined number of magnitude information bits and a second predetermined number of sign information bits per frame, the transmitter including: a magnitude mapping device (50) for mapping the magnitude information bits to the predefined number of symbols; a sign bit encoder (52) for encoding the sign information bits into the predefined number of encoded symbol sign bits per frame; and a signal point selector (54), responsive to the magnitude mapping device and the sign bit encoder, which combines the symbol magnitudes and the encoded symbol sign bits to form the predefined number of transmitted signed symbols per frame.
