Abstract:
1. A receiver, comprising: a blocker cancellation circuit configured to reject an unwanted blocker signal from a received signal received at the receiver based on feed-forward cancellation, wherein the blocker cancellation circuit is configured to substantially isolate the unwanted blocker signal from a remaining portion of the received signal and reject the unwanted blocker signal by removing the isolated unwanted blocker signal from the received signal; and a mixer configured to down-convert the remaining portion of the received signal, wherein the blocker cancellation circuit is further configured to select between a plurality of different receiving modes operating within the same multimode band, and provide feed-forward cancellation processing of the unwanted blocker signal using a compensation method; and wherein the blocker cancellation circuit is enabled for a first receiving mode and disabled for a second receiving mode.
