Figure 16.3 DCast receiver for inter frames.
8-bit integer number and every two integers compose one complex number of 64K
possible values. At last, these complex numbers are passed into a raw orthogonal
frequency division multiplexing (OFDM) module undergoing inverse fast Fourier
transform (iFFT) and D/A conversion for transmission.
The receiver side of DCast is depicted in Figure 16.3. The raw OFDM module per-
forms A/D conversion and ...
