There is a great interest in secure communications within industry and various sectors of society. One common approach of achieving this is by encoding the information using shift-keying methods such as Binary Phase Shift Keying and Quadrature Phase Shift Keying. Proposed in this paper is a new robust yet simple multilevel differential chaotic shift-keying scheme. Compared with the schemes curr...

This paper derives analytically some simple closed form expressions for the average symbol error rate (SER) of M-ary phase shift keying (MPSK), M-ary differential phase shift keying (MDPSK) and noncoherent Mary frequency shift keying (MFSK) over a Nakagami-m fading channel with Lfold maximal ratio combining (MRC) and selection combining (SC) space diversity receptions. Numerical results demonst...

We propose and numerically verify a novel scheme of all-optical format conversion from non-return-to-zero (NRZ) to binary phase-shift- keying (BPSK) at 160 Gb/s using cascaded microring resonators (CMRR) on a single silicon chip. The conversion is based on large phase shift and flattened intensity-response characteristics in the CMRR. A continuous-wave light experiences different phase shifts c...
