Large-scale distributed-antenna system (L-DAS) with very large number of distributed
antennas, possibly up to a few hundred antennas, is considered. A few major issues of the L …

This paper first investigates an M-by-2 massive multiple-input multiple-output (MIMO) system
that transmits a single stream is investigated. For this system, we propose a space-time line …

LTE-Advanced system which based on orthogonal frequency division multiplexing (OFDM)
can eliminate intra-cell interference but still can not mitigate inter-cell interference (ICI) …

Adaptive precoding codebooks are described. In one embodiment, the method of wireless
communication includes reading at least a rank-2 baseline codebook having codewords …

Multiple-input multiple-output (MIMO) orthogonal-frequency division multiplexing (OFDM)
multicasting system is considered. For a real-time multicast MIMO-OFDM system, we …

Distributed transmitter (D-TX) system with multiple distributed TXs is considered. To support
multiple users, the D-TX system employs a zero-forcing based multiuser multiple-input …

In this paper, we consider a distributed transmitter (D-TX) system, in which each TX has a
dissimilar power amplifier with different maximum output power, and different number of …

A method of the multiple input multiple output feedback is disclosed. In accordance with an
embodiment of the invention, the multiple input multiple output feedback method includes a …

This paper describes the design of a time-division duplexing frame with a variety of pilots for
multiuser multiple-input-multiple-output orthogonal frequency-division multiple access (MU …
