Performance of 4- and 8-state TCM schemes with asymmetric 8-PSK in fading channels
For Rayleigh fading channels, Ricean fading channels with a small parameter and shadowed Rician channels with the code design criteria are to maximize the effective length as well as the minimum product distance of the code. In this paper, we use two different asymmetric 8-PSK signal sets in 4-state and 8-state rate 2/3 trellis-coded modulation (TCM) schemes and show performance gain over TCM s...
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 کاملA 4-State Asymmetric 8-PSK TCM Scheme for Rayleigh Fading Channels Optimum at High SNR's
We use an asymmetric 8-PSK signal set in a 4-state rate 2/3 Trellis-Coded Modulation (TCM) scheme for fading channels to show performance gain over known TCM schemes with symmetric and known asymmetric constellations. This scheme is an example of TCM schemes over fading channels where performance gain can be achieved at high SNRs, without increasing the minimum squared product distance, effecti...
متن کاملNew Insight Into The Performance Of TCM Schemes Over Fast Time-Variant Multipath-Degraded Faded Environments1
This work has been partially supported by the European R&D, ACTS-MOSTRAIN program. Abstract The performance Symbol-by-Symbol (SbS) AbendFritchman like combined equalizers/decoders [5] performing diversity reception and coherent detection of Trellis-CodedModulated (TCM) is analyzed for the case of fast time-variant, ISI-corrupted, Rayleigh-faded data-channels. New upperbounds for the resulting d...
متن کاملTCMs Matched to ISI Channels: New Results for Combined Symbol-by-Symbol Equalization and Decoding
(1) This work was partially supported by European Union under the ACTS AC104 MOSTRAIN project. Abstract: The design of good TCM schemes matched to ISI channels requires that analytical performance bounds are also available. In this paper, starting from an application of the unionBhattacharyya bound, upper-bounds for the performance of the theoretically optimum combined Symbol-by-Symbol (SbS) Ab...
