- Frequency Hopping Spread Spectrum, Direct Sequence Spread Spectrum and CDMA
- License: Freeware
- Price: 0.00

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.

- LPC Vocoder GUI
- License: Freeware
- Price: 0.00

An LPC vocoder (Linear-Predictive Coder), is a lossy compression technique that is highly optimized for low-bitrate speech transmission. The problem here that we solve is to take a speech waveform with an 8kHz sampling rate, code it to a much lower bit-rate so that it can be transmitted over a channel, and finally decode it to a signal that is of the same quality.
