Multi-Sparse Signal Recovery for Compressive Sensing
Multi-Sparse Signal Recovery Compressive Sensing Information Theory
2012/6/19
Signal recovery is one of the key techniques of Compressive sensing (CS). It reconstructs the original signal from the linear sub-Nyquist measurements. Classical methods exploit the sparsity in one do...
Mitigating Timing Errors in Time-Interleaved ADCs: a signal conditioning approach
Mitigating Timing Errors Time-Interleaved ADCs signal conditioning approach Information Theory
2012/4/23
Novel techniques based on signal-conditioning are presented to mitigate timing errors in time-interleaved ADCs. A theoretical bound on the achievable spurious signal content, on applying the technique...
The mutual information of bit-interleaved coded modulation (BICM) systems, sometimes called the BICM capacity, is investigated at low signal-to-noise ratio (SNR), i.e., in the wideband regime. A new l...
GPS Signal Acquisition via Compressive Multichannel Sampling
GPS compressive sensing spread spectrum analog compressed sensing
2011/9/14
Abstract: In this paper, we propose an efficient acquisition scheme for GPS receivers. It is shown that GPS signals can be effectively sampled and detected using a bank of randomized correlators with ...
