Course Project:

• Project 1: You will be requested to read, understand, and reproduce the results in the following paper:

        C. Mohanram and S. Bhashyam, “Joint subcarrier and power allocation in channel-aware queue-aware scheduling for multiser OFDM,” IEEE transactions on wireless communications, vol. 6, no. 9, pp. 3208-3213, September 2007.

• A detailed description of the project requirements will follow. However, you must start by reading and understanding the paper thoroughly. You will be required to do coding (Matlab, C, java, etc.) to execute the algorithms and provide results. Students are advised to start NOW.
• There will be one session explaining the needed background in the area of OFDMA, and sub-channel and power allocation.
• Matlab code and resources for Project 1:
  • Matlab Code to generate channel gain to noise power matrix. This code is originally by Zuhang Shen.
  • Matlab Code to find optimal bit loading and power allocation for OFDMA - This code is based on:

   Brian S. Krongold, Kannan Ramchandran, and Douglas L. Jones, "Computationally Efficient Optimal Power Allocation Algorithms for Multicarrier Communication Systems," IEEE TRANSACTIONS ON COMMUNICATIONS, VOL. 48, NO. 1, pp. 23-27, 2000.

  •   Matlab Code to find optimal bit loading and power allocation for OFDMA using exhaustive method and verification of previous code.
