Intercarrier interference in MIMO OFDM
In this paper, we examine multicarrier transmission over time-varying channels. We first develop a model for such a transmission scheme and focus particularly on MIMO OFDM. Using this method, we analyze the impact of time-variation within a transmission block (time variation could arise both from Doppler spread of the channel and from synchronization errors). To mitigate the effects of such tim...
متن کاملOn Out-of-Band Emissions of Quantized Precoding in Massive MU-MIMO-OFDM
We analyze out-of-band (OOB) emissions in the massive multi-user (MU) multiple-input multiple-output (MIMO) downlink. We focus on systems in which the base station (BS) is equipped with low-resolution digital-to-analog converters (DACs) and orthogonal frequency-division multiplexing (OFDM) is used to communicate to the user equipments (UEs) over frequencyselective channels. We demonstrate that ...
متن کاملMassive MIMO for 5G
Massive MIMO is the currently most compelling sub-6 GHz physical-layer technology for future wireless access. The main concept is to use large antenna arrays at base stations to simultaneously serve many autonomous terminals, as illustrated in Figure 1. The rich and unique propagation signatures of the terminals are exploited with smart processing at the array to achieve superior capacity. Mass...
متن کاملMassive MIMO Communications
Every new network generation needs to make a leap in area data throughput, to manage the growing wireless data traffic. The Massive MIMO technology can bring at least ten-fold improvements in area throughput by increasing the spectral efficiency (bit/s/Hz/cell), while using the same bandwidth and density of base stations as in current networks. These extraordinary gains are achieved by equippin...
متن کاملThe Massive Mimo Idea
To achieve the dramatic improvements in capacity and spectral efficiency needed for fifth generation (5G) systems to accommodate the ever increasing number of users who require ubiquitous access to high volumes of wireless data, three symbiotic technological directions are independently emerging [1]: • Increasing frequency reuse through the creation of smaller cells, referred to as picoand femt...
