On Interleaving in Timed Automata [PDF]
, 2006 We propose a remedy to that part of the state-explosion problem for timed automata which is due to interleaving of actions. We prove the following quite surprising result: the union of all zones reached by different interleavings of the same set of transitions is convex.

Interleaver Design for Parallel Concatenated Block Codes With Arbitrary Lengths
IEEE AccessParallel Concatenated Block (PCB) codes are conventionally constituted by two identical linear systematic block codes, as component codes, linked by an interleaver. In general, the PCB code’s interleaver length (or message length) is the square of

Interleaver design methods for turbo codes [PDF]
, 1998 - It is generally assumed that when a turbo decoder is operating at low bit error rates, error sequences have small Hamming weights. From this, and properties of turbo encoders, a mathematical structure is developed for interleaver design, permitting the
