Quasi-Orthogonal Space-Time-Frequency Trellis Codes for MIMO-OFDM Systems
The main objective of this project is to design the full-rate Space-Time-Frequency Trellis code (STFTC), which is based on Quasi-Orthogonal designs for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems. The proposed Quasi-Orthogonal Space-TimeFrequency Trellis code combines set partitioning and the structure of quasi-orthogonal space-frequency desig...
متن کاملCooperative 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 کاملSuper-quasi-orthogonal space-time trellis codes
We introduce a new family of Space-Time Trellis Codes which extends the powerful characteristics of SuperOrthogonal Space-Time Trellis Codes to four transmit antennas. We consider a family of quasi-orthogonal space-time block codes as building blocks in our new trellis codes. These codes combine set-partitioning and a super set of quasi-orthogonal space-time block codes in a systematic way to p...
متن کاملHybrid Concatenated Super-orthogonal Space-time Frequency Trellis Coded MIMO-OFDM Systems
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...
متن کاملSuper Orthogonal and Super Quasi-orthogonal Space-frequency Trellis Coding Using Ofdm for Broadband Wireless Communications
Super-orthogonal and super-quasi-orthogonal space-time trellis coding is seamlessly combined with orthogonal frequency division multiplexing (OFDM) to improve the performance of broadband wireless mobile communication systems. Quadrature amplitude modulation (QAM) is used on all OFDM subchannels. The transmitter is equipped with two antennas when using super-orthogonal space-time trellis codes ...
