Patent ID: 7773698

Claim:
A radio receiver for receiving received signals transmitted via radio, the radio receiver comprising: a first estimating unit for estimating noise power of the received signals as an estimated noise power; a demodulation unit for demodulating the received signals as softbits, wherein the demodulation unit sets a weighting of a least significant bit of the softbits according to the estimated noise power; and wherein the demodulation unit is configured to set the weighting of the least significant bit of the softbits according to an equation: 2 m ≤ N 0 5 where 2 m is the weighting of the least significant bit of the softbits and N 0 is the estimated noise power of the received signals, or wherein the demodulation unit is configured to set a weighting of a most significant bit of the softbits according to an equation: 2 m+M−1 =√{square root over (S 0 )} where 2 m+M−1 is the weighting of the most significant bit of the softbits and S 0 is an estimated signal power of the received signals, or wherein the least significant bit of the softbits is weighted independent of the signal power.
