The objective of the precoding operation is to provide robustness over the fading channel with multipath delay, or to compensate for the unwanted interference The equalization operation estimates the modulated symbols by removing the effect of the channel Through proper design of the precoding operation, equalization sometimes becomes very simple The demodulation operation converts the estimated symbols into a bit format, which is then used to recover the information bits through the channel decoding operation 121 Frequency-Selective Fading Channels In a wireless propagation environment, the signal transmitted arrives at the receiver with multiple delayed and attenuated versions, and these versions are added up and received by the receiver The difference in traveling time, , between the shortest and longest paths is called excess delay spread.

Several experiments have indicated that indeed frequency stabilization of laser diodes by use of external phase-conjugate feedback is possible [122, 124] Figure 449 shows an experimental arrangement to realize phase conjugate feedback The laser diode is a Hitachi HLP1400 laser and it is coupled to a passive ring phase conjugator that uses the photorefractive effect in a BaTiO3 crystal This particular configuration of the phase conjugator has the optic axis, c-axis, oriented as shown in Figure 449 Two mirrors direct the beam back into the crystal and its propagation is restricted to be in the clockwise direction by an optical isolator When the ring is allowed to have counter-propagating beams, the reflectivity is unstable in time [123] The half-wave plate is inserted in the loop to insure that the polarization of the beam is perpendicular to the c-axis for efficient phase conjugation.

The separate use of upstream and downstream channels, as we have seen in Figure 13.2, offers the potential for a 2:1 better use of the spectrum. However, in addition, the fact that, even during a communication, the participants are neither `talking' nor `listening' for a good proportion of the time, leads to a possibility for further statistical multiplexing. This makes for very ef cient carriage of `bursty' data, as we explain next by means of an example.

When the excess delay spread is much smaller than the symbol period, Ts , the channel can be described by a single delay tap With this single delay tap, in the frequency domain, the channel responses are at.

In addition, an etalon is inserted in the external cavity to keep the laser operating on a single longitudinal mode of the solitary laser..
