In this paper, an adaptive space-time receiver for cooperative relay networks is proposed. Using cooperative amplify-and-forward relay nodes, it is possible to increasing the rank of the multiple-input multiple-output (MIMO) channel. The proposed receiver is based on a joint adaptive iterative detection and decoding algorithm, adaptively cancels co-channel interference and eliminates the multiple...
In this paper, VLSI implementation of a configurable, soft-output MIMO detector is presented. The proposed chip can support up to 8 ?? 8 64-QAM spatial multiplexing MIMO communications, which surpasses all reported MIMO detector ICs in antenna number and modulation order. Moreover, this chip provides configurable antenna number from 2 ?? 2 up to 8 ?? 8 and modulation order from QPSK to 64-QAM. Its...
In this paper, we have developed a novel unified approach to deal with arbitrary transmitted power constraints for designing jointly the MMSE precoders and decoders in uplink multiuser MIMO systems. This work is an extension of the first iterative approach developed by Serbetli and Yener for per-user power constraint. An explicit expression relating Lagrange multipliers with the per-user constraint...
