Patent ID: 7916773

Claim:
A method for receiving coded digital data symbols in a receiver circuit of a receiver, comprising the steps of: calculating, by the receiver, 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); providing a scaling factor(s) and using the scaling factor (s) to scale the first symbol estimates, further comprising finding maximum amplitude value (B(S n )) among a of values associated with a group of received data symbols, comparing the maximum amplitude value (B(S n )) with a filtered value (B filter (S n )), wherein the filtered value (B filter (S n )) is calculated based on at least a maximum amplitude value (B(S n−1 )) among a group of values associated with a group of previously received data symbols, if the maximum amplitude value (B(S n )) is lower than the filtered value B filter (S n )), the scaling factor (s) on basis of the maximum amplitude Value (B(S n )), and otherwise providing previous scaling factor (s prev ) which was provided for a group of first symbols estimates associated with a group of previously received data symbols; and truncating the scaled symbol estimates (y sc ) to a second, lower bitwidth (c) and thereby providing second symbol estimates (y t ).
