Combining in Receive Diversity Systems

摘要

A receiver apparatus includes a first receiver having an input for receiving a first version of a signal received by a first receive antenna. The receiver apparatus further includes a second receiver having an input for receiving a second version of the same signal received by a second receive antenna. The first receiver includes a first constellation demapper for demapping constellation symbols generated in the first receiver into a first soft decision bitstream and the second receiver includes a second constellation demapper for demapping constellation symbols generated in the second receiver into a second soft decision bitstream. A combiner is configured to combine the first soft decision bitstream and the second soft decision bitstream to provide a combined soft decision bitstream.
