ABSTRACT A solution of nonlocal EPR correlation between counter-propagating pair of polarization entangled photons emitted from a common source at S and detected at points P and Q is sought outside the EPR’s reality criterion of local causality but within the framework of time-symmetric quantum electrodynamics allowing the bi-directional signal transmission P  S Q on the double-light cone where the future and the past cones share common light paths connecting the photon source S and the detection points P and Q. ...

ABSTRACT In this paper we propose a new class of ternary Zero Correlation Zone (ZCZ) sequence sets based on binary ZCZ sequence sets construction. It is shown that the proposed ternary ZCZ sequence sets can reach the upper bound on the ZCZ sequences. The performance of the proposed sequences set in asynchronous Direct Sequence-Code Division Multiple Access (DS-CDMA) system is evaluated. In the simulation we used two types of channels: Additive White Gaussian Noise (AWGN) and frequ...
