Abstract (en)
[origin: WO0147137A1] A method of selecting a soft symbol for a subsequent operation in a communication device is disclosed. In one embodiment, a signal is received at the communication device. Next, the signal is demodulated. Then, a strength level such as a signal to noise ratio Eb/Nt is determined. Based upon the strength level determined for the signal stored in a register, a location of bits around the average amplitude (451, 452) of the signal is determined for representing the soft symbol in a subsequent operation. The strength level and the location of bits is adaptively updated for the signal over time.
