<p>A mobile station cellular telephone transmitting system (14) having a digital data source (10), waveform map (18), FIR filter with eight taps (24), a zero force circuit (36), start/end burst detection circuit (30), quadrature modulator (46), upconverter (54), and power amplifier (60). The ramping of the power output at the beginning and end of each frame slot or burst is controlled by forcing the first and last symbol of the burst's FIR filter output to zero. <IMAGE></p> |
