Cooperative Orthogonal Space-Time-Frequency Block Codes over a MIMO-OFDM Frequency Selective Channel

In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...

Multiuser Space-Time Block Coded MIMO System with Downlink Precoding

Space-time block codes (STBC) are powerful techniques to achieve full spatial diversity in Rayleigh fading channels with low decoding complexity. When channel state information is available to the transmitter, space-time block codes can be improved through the use of a transmit precoder chosen based in part on the current channel state. In this paper, we investigate the downlink transmission of...

Joint Power Adjustment and Receiver Design for Distributed Space-Time Coded in Cooperative MIMO Systems

In this paper, a joint power allocation algorithm with minimum mean-squared error (MMSE) receiver for a cooperative Multiple-Input and Multiple-Output (MIMO) network which employs multiple relays and a Decode-and-Forward (DF) strategy is proposed. A Distributed Space-Time Coding (DSTC) scheme is applied in each relay node. We present a joint constrained optimization algorithm to determine the p...

Minimum BER Power Adjustment and Receiver Design for Distributed Space-Time Coded Cooperative MIMO Relaying Systems

An adaptive joint power allocation (JPA) and linear receiver design algorithm using the minimum bit error rate (MBER) criterion for a cooperative Multiple-Input MultipleOutput (MIMO) network is proposed. The system employs multiple relays with Distributed Space-Time Coding (DSTC) schemes and an Amplify-and-Forward (AF) strategy. It is designed according to a joint constrained optimization algor...

Adaptive CMMSE Receivers for Space-Time Block Coded MIMO CDMA Systems

A technique that can suppress multiple access interference (MAI) in space-time block coded (STBC) multiple-input multiple-output (MIMO) CDMA systems is developed. The proposed scheme, called the constrained minimum mean square error (CMMSE) receiver, is an extension of the method in [4] to MIMO systems. The proposed CMMSE receiver for STBC systems has the identical complexity and rate of conver...
