Method and apparatus for providing an equalizer that utilizes modified backward substitution for equalization weight matrix generation

A method, comprising:

• receiving a plurality of symbols of an uplink transmission in a wireless communication system having a plurality of subcarriers per a physical resource block (PRB);
• performing an equalization operation on each of the plurality of received symbols of uplink transmission, wherein the equalization operation involves an equalization weight matrix;
• calculating the equalization weight matrix for the equalization operation using a process for inversion of a first matrix, wherein the process includes a modified backward substitution step that calculates a second matrix during calculation of the inversion of the first matrix.
