摘要
A first oscillating signal may be generated via a first direct digital frequency synthesizer of a communication device. One or more second oscillating signals may be generated via one or more second direct digital frequency synthesizers of the communication device. Signals received via a plurality of antennas may be processed utilizing the first oscillating signal. Signals to be transmitted via the plurality of antennas may be processed utilizing the first oscillating signal and the one or more second oscillating signals. The communication device may comprise a plurality of receive channels, a plurality of transmit channels, and a multiplexer. The first oscillating signal may be coupled, via the multiplexer, to the plurality of receive paths and one of the transmit paths. During time intervals in which the communication device is configured to receive signals via the plurality of antennas, the multiplexer may route the first oscillating signal to the first one or more direct digital frequency synthesizers.
