请问 phase error与哪些因素有关啊?

Poor phase error indicates a problem with the I/Q
baseband generator, filters or modulator in the transmitter circuitry. The
output amplifier in the transmitter can also create distortion that causes
unacceptably high phase error. In a real system, poor phase error will reduce
the ability of a receiver to correctly demodulate, especially in marginal signal
conditions. This ultimately affects range.
