Receiver diversity technique for wireless communications

摘要

An electronic circuit for decoding wireless communication signals comprises: a combiner adapted to receive one of an incoming time diverse or frequency diverse signal representing blocks of encoded symbols. The blocks of symbols have been transmitted by a plurality of spatially diverse antennas. The combiner is configured to combine the received encoded symbols. The received encoded symbols include negated selected symbols and conjugated selected symbols. A maximum likelihood detector is configured to receive the one of a time diverse or a frequency diverse signal. The detector receives the combined encoded signals and recovers transmitted signals using a channel transfer function.
