Abstract:
SIC equalizer coefficients for multiple layers are concurrently generated in a manner that reduces computational overhead and complexity. If number of transmit antennas (MT) used exceeds two, matrix inverse(s) are generated by using a modified version of Riccatti Recursion. While producing an inverse matrix using this technique, for an N layer matrix (N being an integer>2), inverse matrixe(s) for layers less than N are also concurrently produced—thus, eliminating the requirement of producing inverse an matrix for each respective layer separately.
