MIMO wireless technology is required to increase the data rates for a broad range of applications, including low cost mobile devices. In this paper we present a very low area reconfigurable MIMO detector which achieves a high throughput of 103Mbps and uses 27 Kilo Gates when implemented in a commercial 180nm CMOS process. The low area is achieved by the proposed in-place architecture. This architecture...
MIMO systems (with multiple transmit and receive antennas) are becoming increasingly popular, and many next-generation systems such as WiMAX, 3-GPP LTE and IEEE802.11n wireless LANs relay on the increased throughput of MIMO systems with up to four antennas at receiver and transmitter. High throughput implementation of the detection unit for MIMO systems is a significant challenge especially for higher...
The VLSI implementation of maximum likelihood (ML) detection for higher order multiple input multiple output (MIMO) systems continues to be a major challenge. Battery driven handheld devices impose strict area and power constraints while demanding guaranteed performance over a wide range of operating conditions. This paper presents a modified, low complexity K-best detector for a 4??4, 64 QAM MIMO...
In this paper, a recursive forward-backward (F-B) trellis algorithm is proposed for soft-output MIMO detection. Instead of using the traditional tree topology, we represent the search space of the MIMO signals with a fully connected trellis and a forward-backward recursion is applied to compute the a posteriori probability (APP) for each coded data bit. The proposed detector has the following advantages:...
