چکیده

In this contribution, we extend the polynomial-based ML approach derived earlier for synchronization purposes to the non-data-aided (NDA) case. We propose a fully digitally implemented synchronization concept using interpolation for jointly estimating the timing and phase. The interpolation methods used in this context can be implemented using the so-called Farrow structure. The ML function is also expressed in terms of the polynomial-based interpolator lter branches. Simulation results for both NDA and DA synchronization principles using two types of interpolators are provided and compared with the theoretical case. We notice that the optimized interpolator performs much better compared to the Lagrange interpolator.

Neural Networks algorithms for Improving Delay Lock Loops Performances for Navigation Satellite Systems in urban environment

1 Abstract In this paper a novel code tracking algorithm is proposed which can be used in GNSS receivers. Classical code tracking approaches consider AWGN channels as an hypothesis for designing theoretically optional trackers. However, this hypothesis does not hold in multipath channels. The method proposed , based on neural networks, provides results that outperform classical DLL trackers. On...

Target Localization in the Presence of Multipaths

A delayed version of a bandlimited signal can be represented by convolving a sinc function and the signal itself. By using this property, a novel constrained LMS algorithm that estimates the difference in arrival times of signal at two spatially separated receivers with multipath propagations is developed. The time delay obtained can be used to localize targets in sonar and radar systems. Intro...

LMMSE receivers performance under non-ideal conditions

Linear minimum mean square error (LMMSE) receivers are capable of suppressing multiple access interference and near-far occurrences in a code division multiple access (CDMA) system operating in multipath fading wireless channels. Their relative low complexity makes them suitable for both uplink and downlink receivers. Third generation receivers are mainly based on coherent detection. Carrier fr...

Time Delay Tracking for Multiuser Synchronization in CDMA Networks

Multipath propagation, multiple access interference and non-line of sight propagation, etc. have impeded the accuracy in mobile data measurements. Multiuser receivers in asynchronous Code Division Multiple Access (CDMA) systems require the knowledge of several parameters such as timing delay between users. In this paper, the problem of time delay estimation for CDMA systems is examined by propo...

Time Estimation of Superimposed Coherent Multipath Signals Using the EM Algorithm for Global Positioning System

A novel multipath mitigation technique for Global Positioning System (GPS) receivers using the Expectation-Maximization (EM) algorithm is proposed. It is well-known that conventional propagation delay estimation using parallel sliding correlators is only optimal in additive white Gaussian noise channel. In practical positioning systems, the weak GPS line-of-sight signal is generally embedded in...
