Transmitter which adjusts peak-to-average power of a multicarrier signal
by switching between a group of channels and a phase-adjusted group of
channels
摘要:
An apparatus (10) for adjusting peak-to-average power of a multicarrier signal. The apparatus (10) comprises a first (26) and second (28) combiner, a phase-changing device (30), and a switch (36). The first combiner (26) receives a first group of channels (20) and a second group of channels (22) and produces a first combined signal (46). The phase-changing device (30) receives the first group of channels (20) and produces a group of phase-adjusted channels. The second combiner (28) receives the phase-adjusted channels and the second group of channels (22) and produces a second combined signal (48), and the switch (36) responds to the first (26) and second (28) combiners and selects at least one of the first (46) and second (48) combined signals.
