Description: 周期图法谱估计需要对信号序列“截断”或加窗处理,其结果是使估计功率谱密度为信号序列真实谱和窗谱的卷积,导致误差的产生。本程序分别设计了周期图法,最大熵功率谱估计和Welch法以及它们的对比,最大熵功率谱估计目的是最大限度地保留截断后丢失的“窗口”以外信号的信息,使估计谱的熵最大。-Periodogram spectrum estimation signal sequence needs to " cut off" or add the window handle, the result is an estimated power spectral density of the signal sequence of the real spectrum and spectral convolution window, resulting in the generation of errors. The procedures were designed periodogram, maximum entropy power spectrum estimation and the Welch method and their comparison, the maximum entropy power spectrum estimation purpose is to maximize the retention of truncated after the loss of the " window" than the information signal, the entropy of the estimated spectrum maximum.

Description: Its a research paper from ieee In this letter, analytical expressions are derived for
the power spectral density (PSD) of orthogonal frequency division
multiplex (OFDM) signals employing a cyclic prefix (CP-OFDM)
or zero padding (ZP-OFDM) time guard interval. Under the relatively
weak assumptions that i) the data are independent and identically
distributed on all OFDM subcarriers and ii) the OFDM
pulse shape is sufficiently localized in time, simple closed-form PSD
expressions can be obtained. These expressions are then compared
to existing OFDM PSD expressions and validated by inspecting the
power spectra of some standardized OFDM signals. Platform: |
