Comparison of the average spectral efficiency of SC-, SEC-, and SECps-based
schemes (all for option 2).
the SEC-based bandwidth-efficient scheme in the high-SNR region. Finally, it is inter-
esting to note that the spectral efficiencies of the SEC-based and SECps-based minimum
estimation schemes for option 2 are exactly the same as one would intuit.
