Performance of tone calibration with frequency offset and imperfect pilot filter [mobile radio]

A relatively complete analytical treatment of TCT (tone-calibrated transmission) error rate is presented. It includes the effects of Rice and Rayleigh fading. frequency offsets, and a selection of nonidealities in the receiver´s pilot tone filter. Such nonidealities are shown to result in the reappearance of an error floor, which is quantified and shown to be insignificant except for extreme fading rates. Comparison with differentially detected PSK (phase-shift keying) shows that TCT provides a lower bit error rate in the noise-limited region and a much lower (by orders of magnitude) error floor in the random FM limited region
