Abstract :
This paper investigates the diversity order of single-carrier, symbol-by-symbol linear equalization (LE). It is shown that minimum mean square error (MMSE) linear equalizers achieve full diversity of v + 1 (the number of channel taps) independent of spectral efficiency. Our results also provide a new proof for the full diversity of decision feedback equalization (DFE), which was shown originally in A. Medles and D.T.M Slock (2004).
