摘要： An electronic device such as a cellular telephone may include transceiver circuitry for handling wireless communications. The transceiver circuitry may include a transceiver such as a cellular telephone transceiver or a wireless local area network receiver and may include a satellite positioning system receiver. Radio-frequency circuitry may be used to couple the transceiver circuitry to antenna structures. When operating the transceiver in different modes of operation, the radio-frequency circuitry may be adjusted to optimize performance. Adjustments to the radio-frequency circuitry may impose phase offsets on satellite positioning system signals that are received through the antenna structures and radio-frequency circuitry. These phase offsets which would otherwise cause degradation in the satellite positioning system receiver can be compensated by applying stored compensating phase offset values to the satellite positioning system receiver during operation.
