Abstract
A receiver (156) includes both a coherent and noncoherent demodulator. When the confidence that estimates of the channel is high, the coherent demodulator is implemented. When the confidence that estimates of the channel is low, the noncoherent demodulator is implemented. A controlling microprocessor (162) controls the selection process and also provides a signal (158) to enable the noncoherent demodulator in instances when noncoherent demodulation would most likely be better than coherent demodulation. As an example, such an instance would be immediately after handoff of a mobile station (505) from a source base-station (503) to a target base-station (502).
