A Root-MUSIC-Like Direction Finding Method for Cyclostationary Signals

A Hermitian Mapping Approach to Unitary Root-music Algorithm for Cyclostationary Signals

By Hermitian mapping, we suggest unitary cyclic root-MUSIC algorithm to exploit the signal selective property of cyclostationary signals in this paper. To deal with correlated or coherent case, we design the forward backward cyclic autocorrelation matrix, without conjugate centrosymmetric array configurations. Compared with unitary root-MUSIC algorithm, the proposed method has a better performa...

Selective direction finding for cyclostationary signals by exploitation of new array configuration

This paper presents a new cyclic direction-of-arrival (DOA) estimation algorithm. By exploiting a new minimum-redundancy linear-array (MRLA) configuration and cyclostationarity, the proposed algorithm constructs a matrix pencil from the pseudodata matrix of 2N-1 virtual sensors which are the results of temporal and spatial processing with designed M-sensor SumMRLA. Theoretical analysis and comp...

Direction Finding Estimators of Cyclostationary Signals in Array Processing for Microwave Power Transmission

A new root-based direction-finding algorithm

[1] Polynomial rooting direction-finding (DF) algorithms are a computationally efficient alternative to search-based DF algorithms and are particularly suitable for uniform linear arrays of physically identical elements provided that mutual interaction among the array elements can be either neglected or compensated for. A popular algorithm in such situations is Root Multiple Signal Classificati...

Variability Method for Cyclo-period Estimation of Cyclostationary Signals

This paper presents a new method, named as the variability method, to estimate the cyclo-period of a discrete-time cyclostationary signal. The method is essentially based on the time-varying correlation and/or mean, whose estimators are associated with some statistics of blocked signals; a plot of variability of these statistics as a function of the blocking operator index visually reveals a pe...
