Abstract :
Computation of MIMO equalization matrices is a critical and computationally intensive part of todaypsilas and future MIMO-OFDM receivers. We present a novel algorithm for computation of the MMSE MIMO equalizer matrix which, compared with the state of art, reduces the number of multiplications by 10% while also featuring innermost loops of a fixed length, allowing for unrolling and easy implementation in custom hardware or on vector processors.
