Thesis Abstract:

Broadband access is known as a way to provide high speed internet access in the residential as well as small and medium sized enterprise sectors. At this moment, cable and digital subscriber line (DSL) technologies are providing broadband services in these sectors. But some practical difficulties have prevented them from reaching many potential broadband internet customers, as many areas throughout the world currently are not under broadband access facilities. However the use of broadband wireless access can overcome these problems.

Different IEEE broadband wireless access standards have been defined, each for a special purpose. IEEE standards 802.11 and 802.16 are two examples, which the former is used for local area networks and the latter is a metropolitan area network that provides the fixed users with BWA services. With the increase of the applications of internet, the need for a new network with the capability of providing mobile users in high speed, with broadband services was a matter of request. So the IEEE standard group introduced the new standard of 802.20. In addition to the capability of supporting high-speed mobile users, because of the high data rate of the standard, it was announced as an alternative for the 3rd Generation operators.

In this research the IEEE 802.20 standard and specially the features of the transceiver of the physical layer will be introduced. In the next stage, the floating-point model of the transceiver will be extracted. With the simulation of this model, a complete comprehension of the behavior of the system and specifications of the physical layer will be obtained. But the implementation of the floating-point model will result in higher cost, area and power consumption along with lower speed. Therefore, bit-true (fixed-point) model is the choice of implementation. This custom implementation of FPGA or ASIC, optimizes the mentioned items in order to have better implementation factors. So at the final stage of this research, the bit-true model of the system will be extracted. For this purpose a new method will be introduced that optimizes the conversion of floating-point to fixed-point, in terms of required simulation numbers.
