Improved Interference Cancelation Channel Estimation Method in OFDM/OQAM System

Table 1

Comparison of three preambles.

preamble	Pilot overhead	Interference cancelation range	ISI cancelation	ICI cancelation	Interpolation process	PAPR performance
ICM1	Three OQAM symbols	First order neighborhood	Zero preamble	Zero symbol data	need	best
ICM2	Three OQAM symbols	First order neighborhood	Zero preamble	Coefficient symmetry	No need	moderate
ICM3	Three OQAM symbols	First order neighborhood	Coefficient symmetry	Coefficient symmetry	No need	worst
