CDMA Spread Spectrum Communications ~ CDMA is a form of Direct Sequence Spread Spectrum communications In general Spread Spectrum communications is distinguished by three key elements The signal occupies a bandwidth much greater than that which is necessary to send the information
Spread Spectrum Communications an overview ~ A spread spectrum communications system is one that is built upon the principle of transmitting information signals over a much wider bandwidth than is strictly necessary for transferring the information By transmitting over a larger bandwidth robustness against external narrowband interference is increased since the wider the bandwidth of any transmitted signal the lower will be the relative influence of interference over a small part of the bandwidth
Spread Spectrum Techniques ~ Principles of CDMA 3 Despreading • At receiver despreading is performed • Example 1tap channel hconstant during transmission • equivalent baseband signal model one sample per chip • received signals during the SF chips of transmitting the spread symbol y hxcn hx hx −hx hx −hx −hx hx −hx T n where n is noise and interference
