Pilot allocation based on users’ location and user classification in massive MIMO system

Aiming at the problem of pilot contamination in massive MIMO systems,a pilot allocation scheme based on users’ location and user classification was proposed.The scheme designed the objective function and reasonable threshold based on path loss and angle of arrival.By comparing the user’s objective f...
