Multiple antenna wireless technology and orthogonal frequency division multiplexing (OFDM) have the potential to enable high data rate wireless applications. While the multiple-input multiple-output (MIMO) wireless techniques exploit spatial domain for improving the quantity and reliability of the data transmitted, OFDM converts the frequency-selective broadband channel into a bank of narrow band...
Multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) has attracted much attention as a solution of high-quality service for next generation wireless communications. However, like OFDM, one of main problems of MIMO-OFDM is the high peak-to-average power ratio (PAPR). In this paper, a novel method to reduce the MIMO-OFDM PAPR is proposed. This method applies space...
This paper proposes a new systematic design framework called DBOASTBC-OFDM for wideband wireless communications in a MIMO (multiple-input multiple-output) system, which is developed from combining the orthogonal frequency division multiplexing (OFDM) with the diagonal block orthogonal algebraic space-time block code (DBOASTBC) and belongs a kind of MIMO-OFDM multicarrier systems. The methods of encoding...
This paper presents a new blind carrier frequency offset estimation scheme for orthogonal frequency division multiplexing (OFDM) systems with constant modulus (CM) signaling. We consider both single-input single-output (SISO) systems and multiple-input multiple-output (MIMO) systems with orthogonal space-time block coding. The proposed scheme is based on the reasonable assumption that the number of...
