Generalized analysis of MU-MISO time reversal-based systems over correlated multipath channels with estimation error
In this letter, we analyze the performance of multi-user multiple-input single-output time reversal (MU MISO TR)-based systems in a generalized framework. The considered propagation is correlated in both the space and the frequency domains, and channel estimation errors (CEEs) at the transmitter...

| description | In this letter, we analyze the performance of multi-user multiple-input single-output time
reversal (MU MISO TR)-based systems in a generalized framework. The considered propagation is
correlated in both the space and the frequency domains, and channel estimation errors (CEEs) at the
transmitter side are also taken into account. We derive a novel average signal-to-interference-plusnoise
(SINR) formula in closed-form for TR-based systems. This formula is based on the exact
expressions of the expectations of the powers of the desired signal, the inter-symbol interference (ISI)
and the inter-user interference (IUI) components. These expressions allow us to reveal, for the first
time, properties of time reversal which remained unknown up to now. More precisely, CEE has no
influence on the ISI in terms of average power, whereas it degrades the power of the desired messagebearing
signal. Moreover, irrespective of the central tap, the other taps of the IUI are independent from
the effects of both inter-user correlation and CEE. Our analytical results are validated in both ultrawideband
and conventional broadband channels. Finally, these results are numerically compared to
previous works. |
