AbstractRecently, the use of space-frequency coding in Orthogonal Frequency Division Multiplexing (OFDM)-based broadband multi-antenna systems has been proposed. The design criteria for space-frequency codes derived in  are vastly different from the well-known design criteria for space-time codes. In this paper, we provide an explicit construction of a class of space-frequency codes which achieve full spatial and frequency diversity.
