Compare in terms of what, performance? Differential will lose
due to noise doubling, and least-squares depends on the quality of
the estimate itself. So it depends on your SNR.

talks about all the different kinds of channel estimation schemes for
OFDM reception. They discount differential modulation, but how does
it compare with the simplest channel estimation techniques: Least
Square (LS)?
