Various example embodiments are disclosed relating to wireless transceivers, such as, for example, wireless MIMO (multiple input multiple output) systems. In an example embodiment, a method may include determining an updated channel frequency response (502), and determining a prefilter for use in a wireless MIMO transmitter based on the updated channel frequency response (504) to reduce an error between transmitted and received signals. The prefilter may include a plurality of decomposed channel matrices, at least one of the decomposed channel matrices may have equal diagonal values (such as, for example, an upper triangular matrix R having equal diagonal values). The prefilter may then be used to process or prefilter a received signal for transmission over a wireless channel.
