    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)

    Main Board

    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:

    U$6500.

    ? 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

    contact with the agents:

    ? 智原科技 : 03-5787888-8345 吳靜虹.

    ? 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. (The partition of the design 10/31/06 set of complete Development should be re-considered again) (3 months) documents as a tutorial (Ph.D × 2 + Code the design in Verilog for those 11/1/06 ~ 8/31/07 Every design passes Master × 6) deterministic modules and in System C (10 months) the local simulation.

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

    picture.

    Presentation 方式及原則:

    1. 不宜用 Power Point (無法置放大圖表), 宜用 WORD.

    2. 將瞭解的部分, 換成簡潔清晰的英文或中文, 條列式的表達.(類似 Power Point 的表

    達方式)

    3. 努力查詢後, 不瞭解的部分, 用其他顏色標註.

    4. 對於太 trivial 的部分(8.4.5), 不必交代的太 detail, 但要說明其功能及在系統中的意

    義為何.
