PSSS modulation is evaluated for high bandwidth millimeter wave communication systems using a 240GHz MMIC based RF frontend. Although the system was restricted to phase modulated signals due to limited linearity when using conventional modulated signals, a transmission using a multivalent PSSS sequence with a spectral efficiency of 1 bit/s/Hz succeeded thanks to the introduced coding gain. At a gross data rate of 20 Gbit/s, an eye opening of 40% and a BER of 5.4x10^-􀀀5 were observed.
