Spatially Sparse Precoding in Millimeter Wave MIMO Systems

This paper considers transmit precoding and receiver combining in mmWave systems with large antenna arrays and develops algorithms that accurately approximate optimal unconstrained precoders and combiners such that they can be implemented in low-cost RF hardware.

Channel Estimation and Hybrid Precoding for Millimeter Wave Cellular Systems

An adaptive algorithm to estimate the mmWave channel parameters that exploits the poor scattering nature of the channel is developed and a new hybrid analog/digital precoding algorithm is proposed that overcomes the hardware constraints on the analog-only beamforming, and approaches the performance of digital solutions.

  • 25 February 2014
A general framework to evaluate the coverage and rate performance in mmWave cellular networks is proposed, and the results show that dense mmWave networks can achieve comparable coverage and much higher data rates than conventional UHF cellular systems, despite the presence of blockages.

Grassmannian beamforming for multiple-input multiple-output wireless systems

A codebook design method for quantized versions of maximum ratio transmission, equal gain transmission, and generalized selection diversity with maximum ratio combining at the receiver is presented and systems using the beamforming codebooks are shown to have a diversity order of the product of the number of transmit and thenumber of receive antennas.

Limited Feedback Hybrid Precoding for Multi-User Millimeter Wave Systems

Analytical and simulation results show that the proposed techniques offer higher sum rates compared with analog-only beamforming solutions, and approach the performance of the unconstrained digital beamforming with relatively small codebooks.

Energy-Efficient Hybrid Analog and Digital Precoding for MmWave MIMO Systems With Large Antenna Arrays

This paper proposes a successive interference cancelation (SIC)-based hybrid precoding with near-optimal performance and low complexity, and proposes a low-complexity algorithm to realize SIC-based Hybrid precoding, which can avoid the need for the singular value decomposition and matrix inversion.

Modeling and Analyzing Millimeter Wave Cellular Systems

A baseline analytical approach based on stochastic geometry that allows the computation of the statistical distributions of the downlink signal-to-interference-plus-noise ratio (SINR) and also the per link data rate, which depends on the SINR as well as the average load is presented.
