Digital modem field test results applicable to the North American digital cellular system and the Japanese digital cellular system are presented. A modem meeting all specifications of the North American digital cellular system is described. The model is designed to identify channel conditions and to choose the appropriate detector operating with or without an equalizer. Measured bit error rate performance of the modem is presented in Rayleigh-faded and delay spread channels. Statistical data show the amount of time the modem required an equalizer detector during field testing. The speech quality outputs of the equalizer and nonequalizer detectors are compared. Diversity receiver performance in Rayleigh-faded and time-dispersive channels is reported
