Abstract	This paper presents a space-time multiple-input and multiple-output (MIMO) transceiver for reliable transmissions over frequency selective fading channels using conventional single-carrier M-ary PSK or QAM modulations. The novelty of the proposed scheme is in efficient exploiting the induced circulant structure of the new signaling in the context of MIMO setup so that the intersymbol interference (ISI) effects could be fully mitigated at the receiver using algebraic solutions. It is demonstrated through Monte-Carlo simulations that the performance of this scheme over time-dispersive channels is comparable to that of MIMO-OFDM. OFDM has high peak to average power ratio (PAPR) and demands the use of highly linear power amplifiers (PA). The proposed scheme offers the advantage of reduced constraints on the PA linearity, which is critical in wireless applications.
