Abstract
A MIMO receiver implements a method for the soft bit metric calculation with linear MIMO detection for LDPC codes, after linear matrix inversion MIMO detection. In the receiver, a detector detects the estimated symbol and the noise variance. Further, a soft metric calculation unit computes the distance between the estimated symbol and the constellation point, and then divides the distance by the noise variance to determine the soft bit metrics.
