Unlike some traditional polynomial phase signal (PPS) parameter estimation methods restricted to monocomponent case, this paper focuses on the parameter estimation of multicomponent PPSs mixed in a single channel, which is more sophisticated and always involves the cross-term issue. In this investigation, based on the model of multicomponent PPSs in additional white Gaussian noise, we partition...

We present a general quantum metrology framework to study the simultaneous estimation of multiple phases in the presence of noise as a discretized model for phase imaging. This approach can lead to nontrivial bounds of the precision for multiphase estimation. Our results show that simultaneous estimation (SE) of multiple phases is always better than individual estimation (IE) of each phase even...

Direction-Of-Arrival (DOA) estimation is one of fundamental but significant techniques for high-speed mobile communication to know wave propagation environment [1]. ”Superresolution” DOA estimation methods such as MUSIC [2], Root-MUSIC [3] and ESPRIT [4] methods are paid so much attention because of their brilliant properties in estimating DOAs of incident signals. Those methods achieve very hi...

This article explores a number of existing project cost estimation techniques to investigate how the estimation can be done in a more accurate and effective manner. The survey looks into various estimation models that utilize many theoretical techniques such as statistics, fuzzy logic, case-based reasoning, analogies, and neural networks. As the essence of conventional estimation inaccuracy lie...

A complete OFDM synchronization chain is proposed based on practical synchronization schemes. The synchronization is accomplished in three steps: frame detection (or timing), frequency offset estimation, and phase tracking. For frame detection, time-domain differential PN sequence is used. For frequency offset estimation, time-domain correlation of adjacent pilot symbols estimates the fractiona...

Parameter estimation of polynomial phase signals (PPSs) is of great interest in various practical applications. In this paper, parametric methods for parameter estimation of polynomial phase signals are discussed and compared. The suboptimal maximum likelihood estimation methods, such as the high-order ambiguity function (HAF) and the product HAF (PHAF) are presented. The polynomial time freque...
