GNURadio默认提供的OFDM调制解调模块见下面的列表。

  1. OFDM Carrier Allocator / OFDM载波分配器
  2. 由复数值创建频域的OFDM符号,添加导频。
  3. This block turns a stream of complex, scalar modulation symbols into vectors which are the input for an IFFT in an OFDM transmitter. It also supports the possibility of placing pilot symbols onto the carriers.
  4. The carriers can be allocated freely, if a carrier is not allocated, it is set to zero. This allows doing OFDMA-style carrier allocations.
