Abstract

A new multiple-antenna transmission framework is proposed for multicarrier multiple-access wireless communication systems. The trilinear tensor (PARAFAC) decomposition is used to model a multiple-input multiple-output (MIMO) space-time-frequency (STF) scheme which consists in jointly multiplexing and spreading multiple data streams across space (transmit antennas), time (chips) and frequency (subcarriers) using a trilinear spreading code. The proposed framework affords a variable degree of diversity across the three signal dimensions by adjusting the dimensions of the trilinear spreading code. It also allows blind detection at the receiver by means of the alternating least squares algorithm.
