Single-Carrier Frequency Division Multiple Access (SC-FDMA) has been adopted as a possible air interface for future wireless networks. It combines most of the advantages of Orthogonal Frequency Division Multiple Access and the low Peak to Average Power Ratio (PAPR) of single carrier (SC) transmission. Existing transmit antenna diversity techniques such as Space-Time Block Coding and Space-Frequency Block Coding are incompatible either with the system constraints or with the SC nature of

... We propose a novel space-frequency flexible coding scheme compatible with SC-FDMA and we prove its good performance both in terms of PAPR and Bit Error Rate (BER) on frequency selective Multiple Input Multiple Output channels.
