The rank revealing QR factorization is a useful tool in many signal processing applications; since it explicitly yields all the necessary information to solve rank deficient least-squares problems and subset selection problems, to compute signal and noise subspaces, etc. The authors present a systolic algorithm for computing a rank revealing QR factorization, and consider the performance of the algorithm.>
