Abstract

When a mobile station is powered on or handed off in future cellular or wireless LAN environment where multi types of cellular and LAN access techniques (CDMA, GSM, 3G. IEEE802.11 etc.) exist, the universal cellular Base Station will select the best combination of the techniques for the mobile station based on the given mobile station size, power, distance and hardware available. The universal cellular Base Station communicates with the mobile station in many access modes, different modulation modes (PSK. QAM. GMSK etc.) and different FEC coding (Reed-Solomon, convolutional etc.). The base station will run a complex budget calculation to find the best modulation type. FEC type and multiple access technique and inform the mobile station about the best possible modes of operation in its cell. This thesis introduces such complex algorithm and gives few results.
