Abstract A modification of transmit filtering in single-carrier (SC) transmission contributes to an improvement of system performance in terms of peak-to-average power ratio (PAPR) and bit error rate (BER). Using minimum mean-square error based frequency-domain equalization (MMSE-FDE) at the receiver can combat the problem of inter-symbol interference (ISI) arising from channel frequency-select...

Abstract The article discusses the results of a practical study method for determining slipping wheels an agricultural tractor using single-frequency GNSS receiver Doppler measurement method. Comparison with standard ISO 789-9 slip

Single-carrier cyclic prefix (SCCP) has been proposed as an alternative to orthogonal frequency division multiplexing (OFDM). While the implementation complexity of the two schemes are comparable, SCCP avoids the peak-to-average power ratio problem that plagues OFDM. Both OFDM and SCCP receivers leverage the fast Fourier transform for computationallyefficient frequency-domain equalization. For ...

Single frequency receivers for Global Navigation Satellite System (GNSS) are low-cost and easily accessible, deeming them cost-effective commercial applications requiring localization tracking. However, the positioning solution these provide must conform to desired reliability standards. A check is essential in signal-degraded environment, where a position fix might be unacceptably inaccurate. ...

background and purpose: the identification of genetics risk factors of human diseases is very important. this study is conducted to model the allele frequencies (afs) of alzheimer’s disease. materials and methods: in this study, several candidate probability distributions are fitted on a data set of alzheimer’s disease genetic risk factor. unknown parameters of the considered distributions are ...

An iterative receiver for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems in time-frequency wireless channels is presented. Multi-User Detection (MUD) and Channel Estimation (CE) are performed using soft information iteratively provided by the single-user decoders. Bidimensional Slepian expansion exploits time and frequency channel variation. Perf...

In this paper, a low voltage ultra-wideband RF receiver for Software-Defined Radio (SDR) is presented. In SDR design, the radio frequency (RF) receiver should be able to receive signals over a broadbandwidth so that it can satisfy a variety of different communication standards. In the proposed design, working frequency ranging from 0.1GHz to 6GHz RF front-end for SDR, covering almost all of mat...
