Generation of optimum excitation waveforms for mobile radio channel sounding

The paper introduces a new development of an existing technique for channel sounding waveform generation. The signal is based on an optimized low crest factor signal which is pre-equalized and predistorted to compensate for the linear and nonlinear elements in the transmitter. The generated signal is such that, at the power amplifier's output, the power spectrum over the bandwidth of interest is uniform and such that there are no out-of-band components. In this way best utilisation is made of the available bandwidth and power. No bandpass filters are required.<
