Modulation Schemes & Relaying Concepts in Mobile WiMAX
Subscribe/Renew Journal
Mobile WiMAX standardized by IEEE 802.16e is a Broadband wireless system based on Scalable OFDMA (Orthogonal Frequency Division Multiple Access). Its main advantage compared to Wi-Fi standard is the possibility of a very powerful handling of radio resources allocation to users in order to adjust quality of radio-environment and number of active users at given area. This paper investigates impact of different modulation schemes & data rates used in Mobile WiMAX to theoretical throughput and deals with efficiency evaluation of these schemes. The aim of this paper is to study the characteristics and utility of relaying in future wireless systems. The focus is mainly on the cooperative principles and relay selection in the case of mobile multihop relay structures.
