AB QR decomposition is a key operation in manycurrent communication systems. This paper shows how to reducethe area of a fixed-point QR decomposition implementationbased on Givens rotations by using a new number representationsystem. This new representation allows performing round-tonearestat the same cost of truncation. Consequently, therounding errors of the results are halved, which allows it toreduce the word-length by one bit. This reduction positivelyimpacts on the area, delay and power consumption of the design.
