An Efficient Detection Technique for SC-FDE Systems with Multiple Packet Collisions
- Usually, packets involved in a collision are lost, requiring the retransmission of all packets. However, if we do not discard collided packets and we use proper retransmissions w...

Time-varying spectrum estimation of uniformly modulated processes by means of surrogate data and empirical mode decomposition
We propose a new estimate of the time-varying spectra of uniformly modulated processes. The estimate is based on a resampling scheme which incorporates empirical mode decompositio...
