Iterative Multi-user Decoding for Mimo-ofdm Systems over Time-frequency Variantwireless Channels
نویسنده
چکیده
An iterative receiver for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems in time-frequency wireless channels is presented. Multi-User Detection (MUD) and Channel Estimation (CE) are performed using soft information iteratively provided by the single-user decoders. Bidimensional Slepian expansion exploits time and frequency channel variation. Performance of the system are presented via numerical simulations.

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 کاملAn Iterative Multiuser Receiver for Space-Time Coded MIMO-OFDM System
Orthogonal frequency division multiplexing (OFDM) is a popular technique to mitigate ISI caused by multipath fading effect of the radio channel. In practice, OFDM could be used in combination with space-time coding, which can be performed in a multiple-input multiple-output (MIMO) system, to increase the diversity gain and/or to enhance the system capacity over timevariant and frequency-selecti...

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...

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
