Weak signal detection performance of selective rake receivers in fading channels
We derive the optimum and suboptimum selective rake receivers (SRRs) for fading environment exhibiting impulsive nature. Simulation results confirm that, when the noise is impuls...

The expansion and mixing time of skip graphs with applications
We prove that with high probability a skip graph contains a 4-regular expander as a subgraph, and estimate the quality of the expansion via simulations. As a consequence skip grap...
