Abstract

A wireless communication device configured for receiving multiple signals is described. The wireless communication device includes a single-chip carrier aggregation receiver architecture. The single-chip carrier aggregation receiver architecture includes a first antenna, a second antenna, a third antenna, a fourth antenna and a transceiver chip. The transceiver chip includes multiple carrier aggregation receivers. The single-chip carrier aggregation receiver architecture reuses at least one of the carrier aggregation receivers for secondary diversity.
