bionet.ted.asdm.asdm_decode_pop(s_list, dur, dt, bw, b_list, d_list, k_list, sgn_list=[])

Multi-input single-output ASDM time decoding machine.

Decode a signal encoded by an ensemble of Asynchronous Sigma-Delta Modulators.

Parameters:

s_list : list of ndarrays of floats

Signal encoded by an ensemble of encoders. The values represent the time between spikes (in s). The number of arrays in the list corresponds to the number of encoders in the ensemble.

dur : float

Duration of signal (in s).

dt : float

Sampling resolution of original signal; the sampling frequency is 1/dt Hz.

bw : float

Signal bandwidth (in rad/s).

b_list : list of floats

List of encoder biases.

d_list : list of floats

List of encoder thresholds.

k_list : list of floats

List of encoder integration constants.

sgn_list : list of integers {-1, 1}

List of signs of first spikes in trains.

Returns:

u_rec : ndarray of floats

Recovered signal.

Notes

The number of spikes contributed by each neuron may differ from the number contributed by other neurons.
