Optimal duration five bit orthogonal chaotic vector shift keying communication: a case study

Publication Date
  • Astronomy


This paper presents a case study of three different five bit multidimensional constellations using Orthogonal Chaotic Vector Shift Keying (OCVSK); a two dimensional chaotic QPSK equivalent scheme (QCSK), a spherical Triakis Icosahedral scheme and a five dimensional hypercubic constellation. The optimal duration for each signal chip within the scheme is determined, in the light of the perceived noise within the channel, and the results are presented. The conclusion drawn is that the higher the dimension of the scheme and the consequential simplicity of the structure, the greater the noise rejection.
