Initial Development Plan for Mobile WiMAX
1 Development/Verification Platform
The expected platform for project development and verification is the ARM-based platform, as
shown in Figure 1. There are 4 main parts of this platform: Main board, FPGA board, ICE and
Software Tool-Chain Package.
C source code(WiMAX MAC)
Software Tool-FPGA Chain Package:Board
(C - Compiler,WiMAX PHY)Debugger andARM Simuator
AMBA AHB Bus
Other ARM9 CPUPeripheraltestchipICEComponents
High Speed PC interface
Figure 1 ARM-based Platform System
? Main Board: contains ARM9 CPU test chip (ARM-926 EJS is recommended), FPGA
socket and other peripherals. The connection between these components is the AMBA bus
(AHB or APB). A high-speed interface to PC is a plus (PCI is recommended) to facilitate
higher-level application development. Referenced price: U$7000.
? FPGA Board: contains an FPGA chip (Xilinx XC2V6000 or Altera StratixEP1S30 is
recommended). WiMAX PHY will be implemented on this board. Referenced price:
? ICE: is the hardware interfacing between software debugger and the ARM CPU. It is
companion with the software debugger. Referenced price: U$6000.
? Software Tool-Chain Package: Includes the program editor, C compiler, software
debugger and ARM simulator. The ARM simulator is the software alias of the hardware
chip. Initially, MAC development is able to target to the simulator instead of the chip.
Referenced price: U$6500.
The above platform is made by ARM itself. For detail price and deliverable information, please

? 創意電子 : Dr. Wu may provide the way for contact.
There are other companies make ARM-based platform, some locate in Taiwan. However, most of
them have not FPGA board accessories, although the prices are much lower.
2 Proposed Schedule for PHY Development
The following table is the proposed schedule for PHY development (NTHU carry out). Please note
no RF module schedule is set due to the status is still un-clear.
Task Description From ~To Bench Mark Individual Study spec (Section 8.4) and give 8/01/06 ~ Every member has a Module presentations.

2.1 Schedule - Study Specification and Give Presentation (8/1 ~ 10/30)
The specification of OFDMA-based mobile WiMAX is much more tedious than that of
OFDM-based fixed WiMAX (297 pages vs. 66 pages). A thorough study is necessary to have a clear
