An Adaptive Frame-Based Interpolation Method of Channel Estimation for Space-Time Block Codes in Moderate Fading Channels
Abstract -- The application of Orthogonal SpaceTime Block Codes (O-STBC) as the encoding scheme in the presence of "non-quasi-static" fading was considered. A simple and ...

Blind Deconvolution of DS-CDMA Signals by Means of Decomposition in Rank-(1, L, L) Terms
In this paper, we present a powerful technique for the blind extraction of direct-sequence code-division multiple access (DS-CDMA) signals from convolutive mixtures received by an ...

1D Effectively Closed Subshifts and 2D Tilings
Michael Hochman showed that every 1D effectively closed subshift can be simulated by a 3D subshift of finite type and asked whether the same can be done in 2D. It turned out that t...

Lower Bounds for Swapping Arthur and Merlin
We prove a lower bound for swapping the order of Arthur and Merlin in two-round MerlinArthur games using black-box techniques. Namely, we show that any AM-game requires time (t2 )...
