Abstract [en]

Matrix inversion is a key operation in for instance adaptivefilters and MIMO communication system receivers. For ill-conditionedchannel matrices long wordlengths are required for fixed-point implementationof matrix inversion. In this work, the wordlength/error tradeoffsfor matrix inversion using different algorithms with fixed-point andlogarithmic number systems (LNS) are considered. LNS provides higherresolution for small numbers and a larger dynamic range. Also, it willalter the cost of the basic operations in the algorithms. The results showthat also the wordlength required to achieve a comparable error differsignificantly between different algorithms and for most algorithms isreduced for LNS compared to fixed-point.
