In this paper, we jointly design linear source and relay precoders for two-hop MIMO relaying. The involved channels encounter spatially correlated fading, the source data symbols are mutually correlated, and the noises are colored not only at the destination but also at the relay. Two different scenarios of channel state information (CSI) are assumed to be available at the transmitters: full CSI of...
The optimal preceding design to maximize capacity of spatially correlated dual-hop non-regenerative multiple-input multiple-output (MIMO) relaying systems is proposed in this paper. The correlated systems generally have additive colored Gaussian noise (ACGN) at receive terminals and correlated data symbols at the source. By designing the optimal precoder in closed-form to cope with channel correlation,...
This paper investigates orthogonal space-time block code (OSTBC) transmission for multiple-input multiple-output (MIMO) amplify-and-forward (AF) relaying networks composed of one source, K relays, and one destination and with M -ary frequency-shift keying (FSK) modulation. A non-coherent detection scheme is proposed and analyzed in a situation where the fading channels...
Conditional mutual information (CMI) analysis and precoding design for generally correlated wireless multi-hop multi-input multi-output (MIMO) channels are presented in this paper. Although some particular scenarios have been examined in existing publications, this paper investigates a generally correlated transmission system having spatially correlated channel, mutually correlated source symbols,...
This paper investigates multiple-input multiple-output (MIMO) amplify-and-forward (AF) relaying networks with orthogonal space-time block codes (OSTBC) and M-ary frequency-shift-keying (FSK) modulation. A non-coherent detection scheme is proposed and analyzed in a situation where the fading channels undergo temporal correlation. Specifically, the destination employs the linear minimum mean square...
This paper studies the bit error rate (BER) performance of an adaptive decode-and-forward (DF) relaying scheme for a cooperative wireless network operating on independent and identically distributed (i.i.d.) or independent and non-identically distributed (i.n.d.) Rayleigh fading channels. The considered network is with one source, K relays, and one destination in which binary frequency-shift keying...
This paper proposes an optimal training design for an amplify-and-forward (AF) relay system, in which the source, relay, and destination are all equipped with multiple antennas. Examined is the scenario when spatial correlation exists among the multiple antennas employed at each node. By properly exploiting the correlation information, the training design problem is formulated as a convex optimization...
This paper proposes an optimal training design for an amplify-and-forward (AF) relay system in which the source, relay and destination are all equipped with multiple antennas. Examined is the scenario when spatial correlation exists among the multiple antennas employed at each node in the system and such information is properly taken into account in the training design. The training design problem...
Optimal training design and channel estimation for spatially correlated multi-user multi-input multi-output with orthogonal frequency-division multiplexing (MIMO-OFDM) systems is still an open research topic of great interest. This paper applies tractable semi-definite programming to obtain the optimal training signal for the general case of spatial channel correlations for multi-user MIMO-OFDM. The...
