Is the symbol signal to noise ratio of the Hybrid modulation (e.g PQ-mPPM modulation ) the same as that of the single modulation(e.g PPM modulation)?

In my question, the PQ refers to Polarization-division-multiplexed quadrature phase-shift keying, and mPPM means m-ary pulse-position modulation. The two modulation formats can be modulated...
