 * Over-the-air bandwidth: usually 10MHz; scales with system clock
 * Clock frequency: core requires clock running 4x over-the-air bandwidth
 * Modulation support: BPSK, QPSK, 16-QAM, 64-QAM
 * Subcarrier usage: arbitrary combination of modulation per subcarrier
 * Resource usage (XC2VP70): 
   * LUT: 16517
   * FF: 17926
   * SLICE: 13830
   * RAMB16: 77
