A method for the construction of hierarchical generalized space shift keying (GSSK) modulation for unequal error protection
In this paper, we propose a systematic method to achieve two-level unequal error protection (UEP) with generalized space shift keying (GSSK) modulation for multipleinput multiple-output (MIMO) systems. GSSK is a modulation scheme that encodes the source information in the antenna indices. To enable the nonuniform arrangement of the spatial constellation of GSSK modulation, new techniques are ne...
متن کاملAdaptive generalized space shift keying
In this article, we propose a closed-loop precoding method for the Generalized Space Shift Keying (GSSK) modulation scheme, suitable for Multiple-Input-Single-Output (MISO) systems and denoted as adaptive GSSK (AGSSK), which achieves transmit-diversity gains in contrast to GSSK. For the case of a perfect feedback channel, we analytically show that for three and four antennas at the transmitter ...
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 کاملModern coding schemes for unequal error protection
In this thesis, we present modern and efficient channel coding techniques for the protection of user data with heterogeneous error sensitivities. Especially multimedia data being transmitted through communication networks often consist of unequally important parts, such as header information, essential payload, and additional data for increased quality. Protecting all data equally makes the tra...
متن کاملAmplitude Shift Keying & Frequency Shift Keying
Aim: To generate and demodulate an amplitude shift keyed (ASK) signal and a binary FSK signal. Amplitude shift keying-ASK-in the context of digital communications is a modulation process, which imparts to a sinusoid two or more discrete amplitude levels. These are related to the number of levels adopted by the digital message. For a binary message sequence there are two levels, one of which is ...
