Comparison of Various Periodograms for Single Tone Detection and Frequency Estimation
نویسنده
چکیده
Periodogram is a simple and eecient way to detect and estimate parameters of sinusoidal signals. In this paper, we attempt to determine the optimum periodogram implementation for a single real tone detection in the presence of white Gaussian noise, among its variants such as the Bartlett's procedure and Welch method. The possibility of delaying threshold eeect using diierent realiza-tions for frequency estimation is also investigated. Simulation results show that the standard periodogram generally gives the best detection performance and it provides the minimummean square frequency estimation error for all signal-to-noise ratio conditions.

متن کامل9 Power Spectrum and Correlation
he power spectrum reveals the existence, or the absence, of repetitive patterns and correlation structures in a signal process. These structural patterns are important in a wide range of applications such as data forecasting, signal coding, signal detection, radar, pattern recognition, and decision-making systems. The most common method of spectral estimation is based on the fast Fourier transf...
متن کاملSelective Tone Reservation Method for PAPR Reduction of Spatially Multiplexed OFDM Systems
Tone Reservation (TR) is one of the well-known methods for PAPR reduction of Orthogonal Frequency Division Multiplexing (OFDM) systems. In this method some sub-carriers are reserved for PAPR reduction and the symbols in these sub-carriers are selected such that the PAPR of the OFDM frame is minimized. In this paper, the iterative algorithm introduced earlier for TR method in single antenna OFDM...
متن کاملLow-Complexity Real-Time Single-Tone Phase and Frequency Estimation
This paper presents a low-complexity real-time single-tone phase and frequency estimation technique based on zero-crossing detection and linear regression. The proposed zerocrossing phase and frequency estimator fills a gap between lowcomplexity phase locked loop estimation and high-performance maximum likelihood estimation. Similar to a phase locked loop, the zero-crossing phase and frequency ...
متن کاملA Novel Sampling Approach in GNSS-RO Receivers with Open Loop Tracking Method
Propagation of radio occultation (RO) signals through the lower troposphere results in high phase acceleration and low signal to noise ratio signal. The excess Doppler estimation accuracy in lower troposphere is very important in receiving RO signals which can be estimated by sliding window spectral analysis. To do this, various frequency estimation methods such as MUSIC and ESPRIT can be adopt...
