MATLAB Source Code - Issue 381: Deep Learning DNN Based on MATLAB - Sparse Pilot Large-Scale MIMO Channel Estimation System Simulation and Bit Error Rate Curve Output

Operating Environment: MATLAB 2024a 1. Algorithm Description As large-scale multi-antenna communication gradually becomes mainstream, the cost of channel estimation is turning into an “invisible ceiling” for system efficiency. In traditional multi-antenna systems, the base station only needs to estimate the channels of a dozen antennas, and the pilot overhead is still manageable. However, when the … Read more

Understanding All Aspects of WiFi

Origin of WiFi Name The term Wi-Fi is often mistakenly thought to refer to Wireless Fidelity, similar to the historical classification of audio equipment: long-term high fidelity (adopted since 1930) or Hi-Fi (adopted since 1950). Even the Wi-Fi Alliance itself frequently uses the term “Wireless Fidelity” in press releases and documents; in fact, the term … Read more
