Experimental Investigation on Time Reversal Precoding for Space-Time Focusing in Wireless Communications

چکیده
This work presents the results of indoor wideband measurements investigating the spacetime properties of wireless signal transmission with online time reversal precoding. The measurements were conducted using a new time-reversal wideband MIMO channel sounder operating at 2.45 GHz with a bandwidth of 240 MHz. Both line of sight and non line of sight propagation conditions were investigated. Spatial focusing and temporal compression can be seen clearly with time reversal precoding, which may be useful for future wireless systems applications. Channel hardening due to time reversal is also observed under both line and non line of sight conditions.

Miso Precoding for Temporal and Spatial Focusing
Time reversal precoding accomplishes matched-filtering of the channel in wireless communication systems by precoding before every transmit antenna with the time reversed complex conjugate of the wireless channel impulse response. While time reversal maximizes the received signal energy at a single time instant (as with matched filtering) it does not eliminate intersymbol interference. This is e...
متن کاملPerformance 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-...
متن کاملCanceling Interferences for High Data Rate Time Reversal MIMO UWB System: A Precoding Approach
An ultra-high data rate time reversal (TR) multiple-input multiple-output (MIMO) ultra-wideband (UWB) communication system with space-time precoding is proposed. When the symbol duration is set to approach the duration of UWBmonocycles, the data rate is close to the limit, resulting in the severe intersymbol interference (ISI). The zero-forcing (ZF) criterion-based spacetime precoding presented...
متن کاملBlock space-time antenna precoding/decoding for generalized multicarrier communications in unknown multipath
Transmit antenna diversity has been exploited recently to develop high performance space-time coders and simple maximum-likelihood decoders for transmissions over known at fading channels. Relying on block precoding, this paper develops generalized space-time coded multicarrier transceivers appropriate for wireless propagation over frequency-selective (and perhaps unknown) multipath channels. M...

Transmit antenna diversity has been exploited recently to develop high-performance space–time coders and simple maximum-likelihood decoders for transmissions over flat fading channels. Relying on block precoding, this paper develops generalized space–time coded multicarrier transceivers appropriate for wireless propagation over frequency-selective multipath channels. Multicarrier precoding maps...
