A New Data Rate Adaption Communications Scheme for Code-Shifted differential Chaos Shift Keying Modulation
In a binary Transmitted Reference (TR) system each bit is encoded into two wavelets of finite duration. The information is carried by the sign of correlation measured between the two wavelets. The Code-Shifted Differential Chaos Shift Keying (CS-DCSK) modulation scheme transmits the two wavelets in the same time slot and applies two Walsh code sequences to keep the wavelets separated. The CS-DC...
متن کاملA Novel Frequency-modulated Differential Chaos Shift Keying Modulation Scheme Based on Phase Separation∗
In frequency-modulated differential chaos shift keying (FM-DCSK), the separation of the chaotic reference and information-bearing wavelets is performed in time domain. This separation method not only limits the attainable data rate but also demands delay components in transceiver circuits. Due to the fact that wideband radio frequency (RF) delay lines are extremely difficult to implement with C...
متن کاملTheory of polarization shift keying modulation
A rigorous analysis of digital coherent optical modulation schemes using the state of polarization as the modulating parameter is presented, which permits to obtain the exact performance of all the polarization-based modulation schemes proposed in the literature so far, including a differential demodulation scheme, named DPOLSK, which does not require either electrooptic or electronic polarizat...
متن کاملSpace Shift Keying Modulation for MIMO Systems
In this seminar, we introduce a modulation scheme, termed space shift keying (SSK), suitable for multiple-input multiple-output (MIMO) systems. SSK modulation, which is a fundamental component of spatial modulation, inherently exploits fading in wireless communications to provide better performance over conventional amplitude/phase modulation (APM) techniques. In SSK, only the antenna indices, ...
متن کاملApplications of Symbolic Dynamics to Differential Chaos Shift Keying
In this paper we propose an enhanced version of the DCSK (Differential Chaos Shift Keying) scheme where the carrier symbolic dynamics are exploited for conveying useful information. This is achieved by means of a pseudo-chaotic encoder which spreads the input sequence approximating the dynamics of the Bernoulli shift. The information encoded in the pseudo-chaotic carrier is retrieved by using s...
