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 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.
متن کاملEvaluation Performance of OFDM Mutlicarrier Modulation over Rayleigh and RicianStandard Channels Using WPT-OFDM Modulations
Last years, Wavelet Packet Modulation (WPM) or Wavelet Packet Transform based Orthogonal Frequency Division Multiplexing (WPT-OFDM) have been introduced to wired and wireless communication fields as efficient Multicarrier Modulation (MCM) techniques. The wavelets have interesting features such as flexibility, compatibility and localization in both time and frequency domains with no need to use ...
متن کاملPerformance analysis of Multi Carrier CDMA System with DCT-OFDM
In this paper, a precise method for calculating the bit-error rate (BER) of a discrete cosine transform (DCT)-based orthogonal frequency-division multiplexing (OFDM) system on additive white Gaussian noise (AWGN) channels for a Multicarrier-CDMA (MCCDMA) is derived and its BER performance will be compared with the FFT based MC-CDMA. These accurate results are used to examine and compare the BER...
