摘要： Techniques for dynamically selecting a number of downconversion paths used in a variety of receiver, wideband receiver architectures, for example, zero-IF or low-IF. In an exemplary embodiment, a first downconversion path is configured to downconvert a signal derived from an RF signal using a first mixing frequency. A second downconversion path is further configured to downconvert a signal derived from the RF signal using a second mixing frequency distinct from the first mixing frequency. The second downconversion path may be selectively enabled or disabled based on a detected level of an interferer in the frequency spectrum. For example, if the interferer level is less than a predetermined threshold, a fewer number of downconversion paths, for example, one path, may be enabled. If the interferer level is greater than a predetermined threshold, then a greater number of downconversion paths, for example, two or more paths, may be enabled.

摘要： Techniques for using one or multiple downconverters to receive multiple transmissions sent on multiple carriers are disclosed. In an exemplary design, an apparatus includes first and second downconverters. The first downconverter downconverts a first radio frequency (RF) signal when it is selected. The second downconverter downconverts a second RF signal when it is selected. Each of the first and second RF signals includes multiple transmissions sent on multiple carriers to a wireless device. The first downconverter is selected to perform downconversion for the multiple transmissions when at least one criterion is not met. The first and second downconverters are selected to perform downconversion for the multiple transmissions, based on different mixing frequencies, when the at least one criterion is met. The at least one criterion may relate to imbalance between the multiple carriers, received power of a received RF signal, etc.
