The purpose of this article is to propose a CORDIC-based QR Decomposition (CQRD) for MIMO Signal Detector module with qualities of low-resource and low-latency. The design contains four stages with six CORDIC modules in which its hardware architecture employs both vectoring and rotation mode equations. The evaluated results of CORDIC-based QRD prove that the proposed hardware design is high performance, low resource, and low latency. Because of the advantages of CQRD, it is suitable for the signal detector in MIMO systems.
