Web9.3.3 The optical Fourier transform transmitter. To realize an OFDM transmitter with signals such as in Figure 9.3, an optical inverse discrete Fourier transform (OIDFT) processor … WebNov 30, 2024 · The inverse transform sampling algorithm is simple: 1. Generate U∼Unif (0,1)U∼Unif (0,1) 2. Let X = FX-1 (U). Then, X will follow the distribution governed by the CDF FX , which was our desired result. Note that this algorithm works in general but is not always practical.
