Optimal precoding for orthogonalized spatial multiplexing in closed-loop MIMO systems
In this paper, we propose a new precoding algorithm for orthogonalized spatial multiplexing (OSM) systems over flatfading multiple-input multiple-output (MIMO) channels. The OSM sc...

Papillon: Greedy Routing in Rings
We study greedy routing over n nodes placed in a ring, with the distance between two nodes defined to be the clockwise or the absolute distance between them along the ring. Such ...

A symmetric Roos bound for linear codes
The van Lint-Wilson AB-method yields a short proof of the Roos bound for the minimum distance of a cyclic code. We use the AB-method to obtain a different bound for the weights of...

Quadratic Goldreich-Levin Theorems
Decomposition theorems in classical Fourier analysis enable us to express a bounded function in terms of few linear phases with large Fourier coefficients plus a part that is pseu...
