Numerical-Optimization

this code is developed for weak signal detection in impulsive noise environment.

The example below encodes one message words using Reed-Solomon encoder. It then corrupts the code by introducing two errors in the codeword, Then BerMass tries to the connection weight vector A and its roots R that it used to know error location.

Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)
