A new admissible hardware‐efficient adaptive blind sign equalisation algorithm for quadrature amplitude modulation systems is presented. The main idea is to amplify the equalised sequence while constraining it to not to exceed the largest signal amplitude. Simulation results demonstrate improved performance in terms of mean squared error and inter‐symbol interference measures.
