Patent ID: 7379506

Claim:
A radio communication system having a multiple-antenna transmitter that selectably transmits data at least from a first transmit antenna transducer and at least a second transmit antenna transducer for communication to a receiver, an apparatus comprising: an encoder which encodes the data, the data encoded comprises a systematic part and a non-systematic part; a determiner at least adapted to receive indications of channel conditions of each channel upon which data is transmitted by each of the first and at least second transmit antenna transducers, respectively, said determiner for determining at least relative channel qualities of each of the channels; and a data assignor coupled to said determiner to receive indications of determinations made thereat, said assignor for assigning the systematic part of the data encoded by the encoder to at least one of the first and at least second transmit antenna transducers that exhibits better channel qualities, wherein the indications of the channel conditions which said determiner is adapted to receive comprise indications of aggregated energy levels of the data detected at the receiver.
