# Dsss implementation in matlab

The following Matlab project contains the source code and Matlab examples used for dsss implementation.
an implementation of DSSS, can be used to simulate Zigbee

The following Matlab project contains the source code and Matlab examples used for simulink model of a bpsk direct sequence spread spectrum system.
Input is generated using the Random Integer Generator block, converted to polar (with unipolar we get 3 states after multiplication instead of 4), then multiplied with the output of a PN-Generator.

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies.

The following Matlab project contains the source code and Matlab examples used for chaotic map based dsss.
This program deals with Spread spectrum communication systems using chaos as the sequence generators.

The following Matlab project contains the source code and Matlab examples used for frequency hopping spread spectrum, direct sequence spread spectrum and cdma.
These programmes are not heavily commented but infact are very simple and intutive to understand the Frequency hopping and related tasks.

The following Matlab project contains the source code and Matlab examples used for dsss jamming trc april 2014.
In this simulation BER plot of Direct Sequence Spread Signal(DSSS) over QPSK modulation for different Jamming Amplitude.
