Interpolation-Based Efficient Matrix Inversion for MIMO-OFDM Receivers

Category: Desktops, Laptops and OS, Networking and Communications

Overview This paper proposes a new class of computationally efficient algorithms for inverting the channel matrices in zero-forcing MIMO-OFDM receivers. Depending on the number of channel taps and the number of antennas, significant complexity reductions can be realized. For the parameter settings used in the IEEE 802.16 standard, savings of up to 80% over brute-force tone-by-tone inversion can be obtained.
