WiMAX in OFDM Physical layer

1 Objectives:The goal of this thesis is to implement and simulate the OFDM Physical layer specification of IEEE 802.16e-2005. Using Adaptive Modulation Techniques we analyze the performance of OFDM physical layer in mobile WiMAX based on the simulation results of Bit-Error-Rate (BER), Signal-to-Noise Ratio (SNR) and Probability of Error (Pe). The performance...

WiMAX Quality of Services (QoS)

The IEEE 802.16 standard supports up to five QoS classes. The level ofquality of service differentiation is per service flow. Each of the service flowis having one of the scheduling types; best effort (BE), non-real time pollingservice (nrtPS), real-time polling service (rt-PS), extended real-time pollingservice (ert-PS) or unsolicited grant service (UGS).WiMAX provides the five QoS classes through an architecture that is able toprocess requests, perform access control and allocate the required...

WiMax over other technology

Over the last few years many types of broadband access technologies such as DSL (Digital subscriber loop) technology, HFC (Hybrid fiber coaxial) network, FBWAN (Fixed broadband wireless access network) have been implemented.DSL is based on the wired technology, it is quite impossible to provide service to many locations such as rural areas, home users. Besides, an xDSL local loop provides services over long distance decreasing data rate that is a great problem for communication. Moreover, The DSL...

WiMAX Forum

IEEE 802 standards provide only the technology. It is then needed to have other organisms for the certification of conformity and the verification of interoperability. In the case of IEEE 802.11 WLAN, the Wireless Fidelity Alliance (WiFi or Wi-Fi) Consortium had a major role in the success of the WiFi technology, as it is now known. Indeed, the...

Physical Layer or The Physical Layer of WiMAX

The 802.16 Physical Transmission Chains The modulation and OFDM transmission are the major building blocks of the WiMAX PHYsical Layer. The transmission chains of WiMAX are described for both OFDM and OFDMA PHYs. 1 The Global Chains The PHY transmission chains of OFDM and OFDMA are illustrated in Figures 1 and 2. The blocks are the same with the...

Different types of Digital Modulation

1.Digital ModulationsAs for all recent communication systems, WiMAX/802.16 uses digital modulation. The now well-known principle of a digital modulation is to modulate an analogue signal with a digital sequence in order to transport this digital sequence over a given medium: fibre, radio link, etc. (see Figure 1). This has great advantages with regard...
