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...
متن کاملA New Full-Diversity Space-Time-Frequency Block Code for MIMO-OFDM Systems
Multi-input multi-output-orthogonal frequency-division multiplexing (MIMO-OFDM) is known as a proper solution for the wideband wireless communication. Numerous space-frequency block codes (SFBCs) and space-time-frequency block codes (STFBCs) have been proposed so far for implementing MIMO-OFDM systems. In this paper, a new fulldiversity STFBC is proposed for two transmit antennas, which could b...
متن کاملCombined Beamforming with Orthogonal Space Time Block Code for MIMO-OFDM with Simple Feedback
In this paper, we introduce a proposed scheme to enhance the performance of orthogonal space time block code (OSTBC) with four time slots and two antennas by combing OSTBC with random beamforming to can use it in the downlink transmission for a mobile system. Multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) system has been recognized as one of the most promi...
متن کاملSpace-Frequency Block Code with Matched Rotation for MIMO-OFDM System with Limited Feedback
This paper presents a novel matched rotation precoding (MRP) scheme to design a rate one space-frequency block code (SFBC) and a multirate SFBC for MIMO-OFDM systems with limited feedback. The proposed rate one MRP and multirate MRP can always achieve full transmit diversity and optimal system performance for arbitrary number of antennas, subcarrier intervals, and subcarrier groupings, with lim...
متن کاملCooperative Partial Transmit Sequence for Papr Reduction in Space Frequency Block Code Mimo - Ofdm Signal
Orthogonal frequency division multiplexing (OFDM) is a popular method for high data rate wireless transmission. OFDM is combined with antenna to increase the diversity gain to enhance the system capacity on time-variant and frequency-selective channels, resulting in a multiple-input multiple-output (MIMO) configuration. To better handle fading channel, Space frequency block code (SFBC) MIMO-OFD...
