Abstract

Two techniques that facilitate the transmission of linear time-division multiaccess (TDMA) signals from a mobile radio base station are proposed. The Cartesian loop technique is applied in a first-order loop configuration and shown to exhibit an excellent transient response when driven with a rapidly switched TDMA waveform. The practical implementation of a feedforward technique is also discussed and shown to be applicable to multicarrier systems employing dynamic channel allocation. Practical results are presented for both systems
