UEP with Adaptive Multilevel Embedded Modulation for MIMO-OFDM Systems
In this paper, a scalable multimedia system with unequal error probabilities (UEP) is considered. A combination of adaptive modulation and hierarchical (embedded) constellations is implemented to realize three different levels of data priorities. The highest priority data bits spread over all available subcarriers with a relatively low modulation order. The next data levels are embedded on top ...
متن کاملPerformance of Multiple-Input Multiple-Output OFDM with Index Modulation
Multiple-input multiple output orthogonal frequency division multiplexing with index modulation (MIMO-OFDMIM) is novel multicarrier transmission technique which has been proposed recently as an alternative to classical MIMO-OFDM. In this scheme, OFDM with index modulation (OFDM-IM) concept is combined with MIMO transmission to take advantage of the benefits of these two techniques. In this work...
متن کاملBER Analysis of MIMO-OFDM System Using Various Modulation Schemes
Multiple transmit and receive can be used to form multiple input multiple-output (MIMO) channels to increase the capacity and data rate. The key advantage of employing multiple antennas is to get reliable performance through diversity and the achievable higher data rate through spatial multiplexing. In MIMO system, information can be transmitted and received from multiple antennas simultaneousl...
متن کاملTransmission of MIMO - OFDM signal using Optical Link
— Wireless networks have quickly become part of everyday life. Wireless LANs, cell phone networks, and personal area networks are just a few examples of widely used wireless networks. However, wireless devices are range and data rate limited. The research community has spent a great deal of effort on finding ways to overcome these limitations. In other words, high Data-Rate wireless access is d...
