The purpose of this project is to analyse the Potential for Secondary Communication on existing wireless systems.
This is accomplished by reordering of users resources, within the frame, and without interfering in the primary communication. Permutations tables which satisfy the Hamming distance are designed and an error correction code is developed. Two wireless systems are chosen for investigation: WiFi and WiMAX. For WiFi different frames are studied and the most appropriate one is used to apply Secondary Communication. In WiMAX two scenarios are developed and the potential is analysed on each of them considering range and number of users.
Calculations and data analysis are done by using an analytical approach, while simulations are coded in Matlab. The thesis concludes with an overview of the project, as well as a summary of the results obtained to better emphasize the Secondary Communication benefits.
