- W2012193892 abstract "In this paper, we propose a hardware architecture of high-speed sorted QR decomposition for a 4×4 MMSEMIMO decoder. A QR decomposition (QRD) is commonly used in many MIMO detection algorithms. In particular, a sorted QR decomposition (SQRD) is a advanced algorithm to improve a MIMO detection performance. The proposed architecture can decompose an augmented channel matrix for MMSE detection by using modified Gram-Schmidt algorithm with pipelining and resource sharing processing. This architecture can be applied in a high-throughput MIMO-OFDM system such as IEEE802.11n which supports data throughput of up to 600Mbps. We implement the proposed architecture with 334k gates in 90nm CMOS technology. The proposed design can achieve a high performance of up to 50.0 million 4×4 SQRD operations per second with the maximum operating frequency of 300 MHz." @default.
