A fundamental challenge in designing brain-computer interfaces (BCIs) is decoding behavior from time-varying neural oscillations. In typical applications, decoders are constructed for individual subjects and with limited data leading to restrictions on the types of models that can be utilized. Currently, the best performing decoders are typically linear models capable of utilizing rigid timing constraints with limited training data. Here we demonstrate the use of Long Short-Term Memory (LSTM) ne...

We present a scheme for joint sparse-channel recovery and data detection in cyclic-prefix orthogonal frequency division multiplex (CP-OFDM) communication over doubly-spread underwater acoustic channels. Inter-carrier interference (ICI), caused by path-dependent Doppler, results in a non-diagonal channel mixing matrix that makes recovery difficult. To combat the effect of ICI, we consider the sequence of observations from partial interval demodulators, and using a path-based channel model, cast t...
