Spatial Multiplexing Ofdm/oqam Systems with Time Reversal Technique

Orthogonal Frequency Division Multiplexing with Offset Quadrature Amplitude Modulation (OFDM/OQAM) is a multicarrier modulation scheme that can be considered as an alternative to the conventional Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) for transmission over multipath fading channels. In this paper, we investigate the combination of the OFDM/OQAM with Multiple I...

Precoded Spatial Multiplexing MIMO Systems in Time- Varying Fading Channel

Conventional precoded spatial multiplexing multiple-input multiple-output (MIMO) systems using limited feedback are mainly based on the notion of time invariant channels throughout transmission. Consequ-encely, the precoding matrix can be found during the training symbols and used over the subsequent data symbols. In this paper, a more practical system where the channel varies from one block of...

Performance of time reversal precoding technique for MISO-OFDM systems

Time reversal (TR) is considered as a promising technique for green and multi-user communications thanks to its time and space focusing properties. TR can be viewed as a precoding scheme which can be combined with orthogonal frequency division multiplexing (OFDM) and easily carried out in a multiple transmit antenna context. This paper analyzes the performance of TR for a multiple-input single-...

Applying Time-Reversal Technique for MU MIMO UWB Communication Systems

1 Abstract—Time Reversal (TR) is a technique to focus broadband signals tightly in time and space. Previously, this technique has been used in acoustics, medical and especially in underwater communication applications. It is capable of reducing noises, such as: Inter-Symbol Interference (ISI), InterUser Interference (IUI). . . , while the used equipments are more simple than complex Equalizers ...
