In this paper, the performance of space-time coding scheme is investigated over Nakagami fading channels. In the first part, the performance of super-orthogonal space-time trellis code is presented while the performance of its concatenated version is presented in the second part. The concatenation coding scheme with iterative decoding involves convolutional code as the outer code and super-orth...

In this paper, a new technique for the blind estimation of frequency and/or time-selective multiple-input multipleoutput (MIMO) channels under space-time block coding (STBC) transmissions is presented. The proposed method relies on a basis expansion model of the MIMO channel, which reduces the number of parameters to be estimated, and includes many practical STBC-based transmission scenarios, s...

To equalize such long fading channel traditional single carrier time domain equalization becomes infeasible due to its large computational complexity. Single-carri...

New air interfaces are currently being developed to meet the high requirements of the emerging wireless communication systems. In this context, the combinations of the multicarrier (MC) and spread-spectrum (SS) technologies are promising candidates. In this paper, we propose a generic transmission scheme that allows to instantiate all the combinations of orthogonal frequencydivision multiplexin...

In this study, we propose two hybrids concatenated Super-Orthogonal Space-Time Trellis Codes (SOSTTC) applying iterative decoding in Orthogonal Frequency Division Multiplexing (OFDM) over frequency selective fading channels. The coding scheme is based on the concatenation of convolution coding, interleaving and space-time coding along multiple-transmitter/multiple-receiver diversity systems. Th...

In this correspondence, we derive some upper bounds of the rates of (generalized) complex orthogonal space–time block codes. We first present some new properties of complex orthogonal designs and then show that the rates of complex orthogonal space–time block codes for more than two transmit antennas are upper-bounded by 3 4. We show that the rates of generalized complex orthogonal space–time b...
