Abstract:
1. A receiver apparatus for carrier aggregation, comprising: at least an antenna, a first signal processing unit, a routing mixer device, a second signal processing unit and a digital signal processor (DSP); wherein the at least an antenna being configured to receive signals; the first signal processing unit being connected to the at least an antenna and configured to process the signals received by the at least an antenna, the processing by the first signal processing unit comprising overclocking, downclocking, noise suppression, and increasing and lowering of signal level; the routing mixer device further including a plurality of mixer modules and a plurality of current/voltage adders, configured to output none, one or any number of outputs at the current/voltage adders by controlling ON and OFF of the mixers; the second signal processing unit being connected to the routing mixer device and configured to process signals from the routing mixer device, the processing by the second signal processing unit including overclocking, downclocking, noise suppression, increasing and lowering of signal level, signal demodulation, and signal domain conversion; and the DSP being connected to the second signal processing unit and configured to perform subsequent signal processing.
