Journal ArticleDOI
Zero-forcing methods for downlink spatial multiplexing in multiuser MIMO channels
TL;DR: While the proposed algorithms are suboptimal, they lead to simpler transmitter and receiver structures and allow for a reasonable tradeoff between performance and complexity.
Journal ArticleDOI
An introduction to the multi-user MIMO downlink
TL;DR: This article reviews several algorithms that have been proposed with the potential to combine the high capacity achievable with MIMO processing with the benefits of space-division multiple access and describes two classes of solutions.
Journal ArticleDOI
Modeling the statistical time and angle of arrival characteristics of an indoor multipath channel
TL;DR: A model is proposed that employs the clustered "double Poisson" time-of-arrival model proposed by Saleh and Valenzuela (1987), and the observed angular distribution is also clustered with uniformly distributed clusters and arrivals within clusters that have a Laplacian distribution.
Proceedings ArticleDOI
A statistical model for angle of arrival in indoor multipath propagation
TL;DR: In this paper, the authors proposed an extension of the Saleh-Valenzuela model to account for the angle of arrival in indoor environments, and compared the model parameters measured in two different buildings with the parameters presented in the paper.

A set of irregular ldpc codes with random structure and low encoding complexity
TL;DR: A block-cyclic LDPC code (9a, 9b, 9c) has an irregular row or an irregular column weight and includes a parity check matrix and an encoding matrix each of which has a pseudα random structure.
