Transmitter for use in multi-antenna wireless communication system for multi-shed input multi-shed output communication, has symbol generator to generate reference symbols and applying phase shifts to reference symbols respectively

摘要

The transmitter has a reference symbol generator (706) to generate reference symbols for channel estimation. A reference symbol inserter (712) inserts the reference symbol into a stream of information symbols for transmission by an antenna at a symbol time period and frequency. Another reference symbol inserter inserts another reference symbol into stream of information symbols for transmission by the antenna at the symbol time period and frequency. The reference symbol generator applies phase shifts to reference symbols. An independent claim is also included for a receiver.
