On Computational Complexity of Counting Fixed Points in Symmetric Boolean Graph Automata
Abstract. We study computational complexity of counting the fixed point configurations (FPs) in certain classes of graph automata viewed as discrete dynamical systems. We prove t...

Positive circuits and maximal number of fixed points in discrete dynamical systems
We consider a product X of n finite intervals of integers, a map F from X to itself, the asynchronous state transition graph (F) on X that Thomas proposed as a model for the dynam...

Efficient Algorithms for PAPR Reduction in OFDM Transmitters Implemented using Fixed-Point DSPs
OFDM has a very high peak-to-average power ratio. This imposes stringent dynamic range requirements on the analog front-ends of the transmitter and receiver and, if a fixedpoint pr...
