Non-confluence in divisionless P systems with active membranes
We describe a solution to the SAT problem via non-confluent P systems with active membranes, without using membrane division rules. Furthermore, we provide an algorithm for simula...

Level Crossing Rates of MIMO-MRC Ricean Channels and Their Implications on Adaptive Systems
- The second-order statistics of the time varying signal to noise ratio at the output of a multiple-input-multiple-output (MIMO) system with maximal ratio combining (MRC) are analy...

Noncoherent Correlation-Based Communication Systems Choosing Different Chaotic Maps
— This paper proposes a new noncoherent detection system improved based on the differential chaos shift keying (DCSK) and the correlation delay shift keying (CDSK). In this schem...
