Method and apparatus for providing an equalizer that achieves a given precision for non-invertible matrices

A method, comprising:

• receiving a plurality of symbols of an uplink transmission in a wireless communication system;
• performing an equalization operation on the plurality of received symbols of the uplink transmission, wherein the equalization operation performs an inversion of a matrix;
• completing the equalization operation on the plurality of received symbols within a user-specified precision without adding any bit to the user-specified precision when the matrix is non-invertible.
