Exploiting Redundancy in an OFDM SDR Receiver

Figure 8

Theoretical background for equalization: selecting the correct submatrix of channel convolution matrix . The circulant property is a result of cyclic prefix insertion in transmitter and proper subblock selection in the receiver. Vector is transmitter output and receiver input. The bold framing indicates subblock selection. The gray area represents nonzero entries.
