| contents | This letter proposes a Message Passing (MP) based algorithm for demodulating the time-encoded digital modulation signal. The proposed algorithm processes the spikes generated by the Time-Encoding Machine (TEM) directly on a per-spike basis, which enables "on-the-fly" demodulatio with low latency. The computational complexity of our proposed method scales linearly with the number of demodulated symbols, while the computational complexity of the pseudo-inverse-based method scales cubically with the same number of demodulated symbols. |
