METHOD AND APPARATUS FOR SCALING SOFT BITS FOR DECODING

摘要

A method and apparatus for scaling a soft bit for decoding in a wireless communication system are described. A scaling factor is calculated for a received symbol based'on an estimated signal-to-noise ratio (SNR) of the received symbol and the scaling factor is applied to a soft bit of the received symbol. A multiple-input multiple-output (MIMO) scheme may be implemented to transmit multiple data streams. In such case, a soft bit of a received symbol on each data stream is scaled by a scaling factor for the received symbol on each data stream.
