Abstract

This letter presents and analyzes orthogonal frequency-division multiplexing\n(OFDM)-based multi-carrier transmission for cell-free massive multi-input\nmulti-output (CFmMIMO) over frequency-selective fading channels.\nFrequency-domain conjugate beamforming, pilot assignment, and user-specific\nresource allocation are proposed. CFmMIMO-OFDM is scalable to serve a massive\nnumber of users and is flexible to offer diverse data rates for heterogeneous\napplications.\n
