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.

The DEMO includes 5 feature selection algorithms: * Sequential Forward Selection (SFS) * Sequential Floating Forward Selection (SFFS) * Sequential Backward Selection (SBS) * Sequential Floating Backward Selection (SFBS) * ReliefF Two CCR estimation methods: * Cross-validation * Resubstitution After selecting the best feature subset, the classifier obtained can be used for classifying any pattern.

This folder contains two simple functions (zerocross and energy) to compute STE and STZCR. The script zcr_ste_so.m uses these two and other functions (included) to compute the STE and STZCR of the word 'so'. See the respective function help for more details.

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.

The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear (http://en.

The pulse generator included in Simulink does not provide the ability to programmatically set the parameters. This block provides inputs that allow the amplitude, pulse width, and pulse period to be set. It's fairly simple, but wasn't obvious to me so I thought I'd share it.
