Autocorrelation algorithm for speech pitch detection based on matlab
的語音信號自相關基音檢測 -
Two detection methods of chirp signals are presented in the dissertation : the cyclic autocorrelation detection method and the correlation detection method of cyclic autocorrelation function. it is shown that the two methods both have an excellent performance of blind detection. the performance analyses of the two detection methods are both carried out for additive noise or multiplicative noise, and the output signal - to - noise ratio ( snr ) expressions of the two methods are also derived
通過研究提出了兩種線性調頻信號的檢測方法?基於循環自相關函數包絡的檢測方法和基於循環自相關函數的相關函數包絡的檢測方法，兩種方法均可實現信號的盲檢測，有良好的檢測性能，文中還分析了加性噪聲及存在乘性和加性噪聲情況下兩種檢測方法的性能，推導出了輸出信噪比公式。 -
For fh signals, we proposed two algorithms too, one is a signal detection algorithm based multiple - hop autocorrelation ( mhac ) of fh signals, and the other is a parameter estimation algorithm based on time - frequency analysis
對跳頻（ fh ）信號，本文提出了基於多跳自相關的信號檢測方法和基於時頻分析的跳頻參數估計方法。 -
The correlation detection using the periodicity of the direct sequence autocorrelation function can estimate the symbol period at intermediate frequency or at baseband. simulation results indicate that the former is superior to the latter when the demodulated frequency is unequal to the carrier frequency
