Query: SER Analysis for SWIPT-Enabled Differential Decode-and-Forward Relay
  Networks   In this paper, we analyze the symbol error rate (SER) performance of the
simultaneous wireless information and power transfer (SWIPT) enabled three-node
differential decode-and-forward (DDF) relay networks, which adopt the power
splitting (PS) protocol at the relay. The use of non-coherent differential
modulation eliminates the need for sending training symbols to estimate the
instantaneous channel state information (CSI) at all network nodes, and
therefore improves the power efficiency, as compared with the coherent
modulation. However, performance analysis results are not yet available for the
state-of-the-art detectors such as the maximum-likelihood detector (MLD) and
approximate MLD. Existing works rely on the Monte-Carlo simulation method to
show the existence of an optimal PS ratio that minimizes the overall SER. In
this work, we propose a near-optimal detector with linear complexity with
respect to the modulation size. We derive an approximate SER expression and
prove that the proposed detector achieves the full diversity order. Based on
our expression, the optimal PS ratio can be accurately estimated without
requiring any Monte-Carlo simulation. We also extend the proposed detector and
its SER analysis for adopting the time switching (TS) protocol at the relay.
Simulation results verify the effectiveness of our proposed detector and the
accuracy of our SER results in various network scenarios for both PS and TS
protocols.
