AIC Method



Random Modulation

- signal sparsity is reconstructed using partial measurements

- affected by design imperfection

modulated wideband converter (MWC)

- robustness against the noise and model mismatches.

- reduction in the measurement matrix dimensionality

- requires large number of low pass filters

Multi-coset sampler

- the sampling rate in each channel is lower than the Nyquist rate

- less measurements

- the channel synchronization should be met to satisfy a specific sampling pattern for robust spectral reconstruction

- requires many sampling channels

Multi-rate Sampling

- Low sampling rate

- Less sampling channels

- stringent implementation
