TL;DR: Novel nondata-aided algorithms are proposed for joint estimation of timing and carrier phase in minimum-shift keying (MSK)-type modulations and compared with that of other existing estimation schemes.
Abstract: Novel nondata-aided algorithms are proposed for joint estimation of timing and carrier phase in minimum-shift keying (MSK)-type modulations. The performance with MSK and Gaussian MSK is assessed by computer simulations and compared with that of other existing estimation schemes.

TL;DR: A simple method for the evaluation of the error rate performance of OFDM signals transmitted over doubly-selective fading channels is described and results are exemplified by simulation results.
Abstract: A simple method for the evaluation of the error rate performance of OFDM signals transmitted over doubly-selective fading channels is described. The accuracy of the proposed technique is exemplified by simulation results. Power series models for multipath channels are employed to derive simple expressions for the average signal-to-interference ratio (SIR) and the average error probability.

TL;DR: Reduced complexity statistical models for the representation of wide sense stationary-uncorrelated scattering (WSS-US) doubly-selective fading channels are developed based on the evaluation of Fourier integrals by means of Gaussian quadrature rules.
Abstract: In this paper reduced complexity statistical models for the representation of wide sense stationary-uncorrelated scattering (WSS-US) doubly-selective fading channels are developed. Their derivation is based on the evaluation of Fourier integrals by means of Gaussian quadrature rules (GQRs). The accuracy and the complexity of the proposed models are assessed and are compared with that provided by other modelling techniques available in the literature.

TL;DR: A novel two-stage noncoherent receiver for interleaved trellis-coded CPFSK signals transmitted over time-selective channels that outperforms previous noncoherence receivers with a moderate increase in complexity.
Abstract: We propose a novel two-stage noncoherent receiver for interleaved trellis-coded CPFSK signals transmitted over time-selective channels. The first stage of the receiver computes reliability information about the transmitted symbols and delivers it to the second stage which operates as a trellis decoder. Simulation results show that the proposed detection strategy outperforms previous noncoherent receivers with a moderate increase in complexity.

TL;DR: In this paper, an optimum one-shot detection over known and partially known doubly-selective Rayleigh fading channels is investigated, based on GQR (Gauss quadrature rules) and power series channel models.
Abstract: In this paper optimum one-shot detection over known and partially known doubly-selective Rayleigh fading channels is investigated. The performance analysis of the detection algorithms is based on GQR (Gauss quadrature rules) and power series channel models. The proposed methods allow to assess the implicit diversity gain provided by both channel multipath and signal fading and the energy loss due to the mismatch of the receiver filter.
