Cross Spectral Density Analysis for Various Codes Suitable for Spread Spectrum under AWGN conditions with Error Detecting Code
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
CDMA is based around the use of direct sequence spread spectrum techniques. Essentially CDMA is a form of spread spectrum transmission which uses spreading codes to spread the signal out over a wider bandwidth then would normally be required. By using CDMA spread spectrum technology, many users are able to use the same channel and gain access to the system without causing undue interference to each other. Here this paper concentrates on the area where how to spread the signal with spread codes, So that more number of users can be accommodated in the spreaded bandwidth. Analyzing various correlation properties comparision between Pseudo Noise and Gold codes, to conclude which code best suits. Walsh Hadmard code has the capability of error detection and correction capability. The codes are simulated using MATLAB.
