Performance 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 کاملDifferential Modulation Diversity for OFDM
The application of differential modulation diversity (DMD) to orthogonal frequency division multiplexing with multiple transmit and/or receive antennas is considered. Based on diagonal signals originally designed for differential space-time modulation, DMD is used to exploit both space and frequency diversity. At the receiver, low-complexity decision-feedback differential detection without chan...
متن کاملOFDM systems with multiple trellis coded modulation
In an attempt to improve the performance under frequency selective fading environment, we propose in this paper an Orthogonal-Frequency-Division-Multiple-Access (OFDM) system in which MTCM (Multiple Trellis Coded Modulation) is applied to a set of multiple subcarriers. The code is designed to enlarge the summation of the Euclidean distance and the product distance. We also propose a scheme for ...
متن کاملAdaptive OFDM Index Modulation for Two-Hop Relay-Assisted Networks
In this paper, we propose an adaptive orthogonal frequency-division multiplexing (OFDM) index modulation (IM) scheme for two-hop relay networks. In contrast to the traditional OFDM IM scheme with a deterministic and fixed mapping scheme, in this proposed adaptive OFDM IM scheme, the mapping schemes between a bit stream and indices of active subcarriers for the first and second hops are adaptive...
متن کاملModulation-index Estimaton in a Combined Cpm/ofdm Receiver
In this paper we develop a blind modulation-index estimator for a combined CPM/OFDM Receiver. The performance of the estimator in an AWGN channel is assessed by simulation and analysis and its suitability for our receiver is established.
