摘要

This brief presents the efficient VLSI implementation of coordinate rotation digital computer (CORDIC)-based sorted QR decomposition (SQRD) for multiple-input and multiple-output (MIMO) systems. SQRD is widely adopted in MIMO signal processing to mitigate error propagation. However, its iterative sorting process after every column annihilation requires a large hardware overhead and suffers from a ...
