Iterative Interference Cancellation for Time Reversal Division Multiple Access

Time reversal (TR) has been proposed as a competitive precoding strategy for low-complexity devices relying on ultra-wideband waveforms, it shifts the signal processing complexity to transmitter side. This transmit paradigm can address need low-power, receivers, which is particularly important Internet of Things. Due its spatio-temporal focusing property, TR also used design multiple access schemes multi-user scenarios. However, with time-division access, signals received by users suffer from significant level inter-symbol interference and inter-user interference, often requires additional at receiver paper proposes an iterative scheme that aims reduce while keeping only The performance this protocol evaluated using analytical derivations. Its superiority over conventional TRDMA demonstrated through simulations experimental measurements.
