Massive MIMO Multicasting in Noncooperative Multicell Networks

by Zhengzheng Xiang, Meixia Tao, Xiaodong Wangy
"... Abstract—We study the massive MIMO (multiple-input multiple-output) multicast transmission in multicell networks, where each base station (BS) is equipped with a large-scale antenna array and transmits a common message using a single beamformer to multiple mobile users. We first consider the case wh ..."

Data Throughputs Using Multiple-Input Multiple-Output (MIMO) Techniques in a Noise-Limited Cellular Environment

by Severine Catreux, Peter F. Driessen, Larry J. Greenstein - IEEE Trans. Wireless Commun , 2002
"... Abstract—We present a general framework to quantify the data throughput capabilities of a wireless communication system when it combines: 1) multiple transmit signals; 2) adaptive modulation for each signal; and 3) adaptive array processing at the receiver. We assume a noise-limited environment, cor ..."

establish and solve a decentralized optimization problem for the case of multiple-input single-output (MISO) channels, introducing a new precoding design metric called signal to generated interference plus noise ratio (SGINR). By extending the result to general MIMO channels, we propose an SGINR

A hybrid probabilistic data association-sphere decoding for multiple-input-multiple-output systems

by Georgios Latsoudas, Nicholas D. Sidiropoulos, Senior Member - IEEE Sig. Proc. Letters , 2005
"... Abstract—A hybrid probabilistic data association (PDA)-sphere decoding (SD) algorithm is proposed for signal detection in multiple-input–multiple-output (MIMO) systems. The key idea is to reduce the dimension of the problem solved via SD by first running a single stage of the PDA to fix symbols that ..."
