The correlation function calculated from one realization of an ensemble is inherently flawed since the expectation operation does not come into play. Hence it is important to have an idea of the variance in the correlation function..

- Sum of harmonics
- License: Freeware
- Price: 0.00

For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that: - The frequencies of the harmonic components are unevenly spaced - The time vector is unevenly spaced In such cases we could be in the need of coding the summation directly in Matlab, that is quite slow in performing this tasks.

- Frequency Hopping Spread Spectrum, Direct Sequence Spread Spectrum and CDMA
- License: Freeware

These programmes are not heavily commented but infact are very simple and intutive to understand the Frequency hopping and related tasks. I have made two files for frequency hopping, one of them is not showing 6 proper impulsive peaks but other programme is infact showing them, In DSSS i have generated 20 bits and each bit is 6 units long and then it is XORed with another pseudorandom data bits and then it is BPSK modulated and hence two peaks in its FFT are displayed.
