ABSTRACT:
A method and a receiver for receiving coded digital data symbols sent from a transmitter through a transmission channel of a communications network is adapted to calculate first symbol estimates (y) of sent data symbols from the received data symbols, each of the first symbol estimates (y) having a first bitwidth (a+b), provide a scaling factor (s) and using the scaling factor (s) to scale the first symbol estimates, truncate the scaled symbol estimates (ysc) to a second, lower bitwidth (c) and thereby providing second symbol estimates (yt).
