Differential chaos shift keying modulation for cooperative and spatial diversity communication systems

Abstract

Chaotic signals are unstable and aperiodic making them naturally harder to identify and predict It has wideband characteristic it is resistant against multipath fading and it offers a cheaper solution to traditional spread spectrum systems In this thesis the performance of differential chaos shift keying DCSK modulation is analyzed in different wireless communication scenarios First a relay selection based DCSK cooperative diversity scheme namely DCSK selection relaying DCSK SR schem
