Abstract
A device and method for preceding data signals for pulse code modulation (PCM) transmission includes a transmitter for transmitting a sequence of analog levels over an analog channel to a quantization device, wherein the analog channel modifies the transmitted analog levels, the transmitter comprising: a mapping device for mapping data bits to be transmitted to a sequence of equivalence classes, wherein each equivalence class contains one or more constellation points; and a constellation point selector interconnected to the mapping device which selects a constellation point in each equivalence class to represent the data bits to be transmitted and which transmits an analog level that produces the selected constellation point at an input to the quantization device.
