Massive MIMO Channel Modeling and Measurements
Summary
Massive multiple-input multiple-output (MIMO) technology exploits large antenna arrays at a base station to serve many users simultaneously, offering significant gains in spectral and energy efficiency. Accurate channel modelling is essential to predict propagation characteristics—such as spatial correlation, delay and angular spreads—and to design robust beamforming and precoding strategies. Complementary measurement campaigns in indoor, outdoor and mixed scenarios validate and refine these models, revealing phenomena such as user channel correlation, frequency selectivity and the impact of array geometry. Together, modelling and measurement underpin the development of next-generation wireless systems, from 5G to 6G, guiding network planning, performance evaluation and spectrum-efficient system deployment in both urban macrocells and dense indoor environments.

Massive MIMO Channel Modeling and Measurements publication trend
The graph below shows the total number of articles in massive mimo channel modeling and measurements across all publications each year (not limited to Nature Index journals).
Technical terms
Massive MIMO: Wireless technology using very large antenna arrays to serve multiple users simultaneously for improved capacity.
Channel model: Mathematical representation of radio-wave propagation capturing parameters such as path loss, delay spread and spatial correlation.
Spectral efficiency: Measure of information rate achieved per unit bandwidth, expressed in bits per second per hertz.
Favourable propagation: Condition in which user channels are nearly orthogonal, enabling high multiplexing gains in MIMO systems.
Coherence bandwidth: Frequency range over which the channel response is approximately constant, determining subband design.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
