The size of the data transmitted in communication systems is constantly increasing and leads to the need for high bandwidth. Therefore, using the millimeter wave (mmWave) band is one of the best solutions in data transmission. Frequency multiplication via nonlinear components is used for signal generation at higher frequencies in the millimeter to submillimeter bands and it is of great importance in generating signals up to 2.2 THz. Although, communication systems with the highest carrier frequency using these components are available at the 300 GHz-340 GHz, standard communication models do not comply with data transmission at this band, bringing problems caused by nonlinearity throughout data recovery. We solve these problems with the proposed constellation modification method, which has not been studied before. In this study, it is aimed to provide data transmission in the mmWave band with an experimental communication system that is compatible with the frequency multiplication and has high spectral efficiency. For the first time to our knowledge, a novel constellation modification method that can be modified according to the frequency multiplication on the standard M-ary phase shift keying (MPSK) data is proposed. In this method, the existing receiver structure is preserved and MPSK with harmonic modulation is carried. In the experimental demonstration part, harmonic binary shift keying (BPSK) data transmission via frequency multiplied 30 GHz transmitter was achieved with a power penalty of 2.3 dB, and this shows that MPSK data transmission over harmonic mmWave or submillimeter band sources is now possible.
