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 کاملPerformance analysis of Adaptive Switching Between Space-Time and Space-Frequency Block Coded OFDM Systems using ZF and MMSE techniques
This paper focuses on the implementation and performance analysis of adaptive switching between STBC and SFBC OFDM systems [1].Here in this paper we proposed an adaptive transmission technique for MIMO OFDM systems using adaptive equalization algorithms (ZF,MMSE) where the channel response are unknown a priori and time variant. In this paper two selection criteria, correlation of the channel an...
متن کاملMultilayered Space-Frequency Block Coded OFDM Systems
In this paper, we propose a multilayered spacefrequency block coded OFDM system, which is a combination of the vertical layered space-time architecture, known as V-BLAST, and the space-frequency block coded OFDM system. This system is designed to provide reliable as well as very high data rate communications over frequency-selective fading channels with low decoding complexity. Orthogonal Frequ...
متن کاملSpace frequency block codes and code division multiplexing in OFDM systems
Abstract— This paper investigates different diversity concepts for OFDM systems. These are space frequency block codes (SFBC) and code division multiplexing (CDM). The performance of both and of combinations of both is compared for coded OFDM systems in a Rayleigh fading channel. The SFBCs and CDM applied in this paper have in common that they have no rate loss and thus do not decrease the band...
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...
