Rewrite the MATLAB simulation of Computer Example 4.3 for the case of an absolute-value type of nonlinearity. Is the spectral line at the bit rate stronger or weaker than for the square-law type of nonlinearity?
Example 4.3
To demonstrate the first method, we assume that a data signal is represented by an NRZ signal that has been band limited by passing it through a band limited channel. If this NRZ signal is squared, a component is generated at the symbol frequency. The component generated at the symbol frequency can then be phase tracked by a PLL in order to generate the symbol synchronization, as illustrated by the following MATLAB simulation:
