Patent ID: 7095731

Claim:
A method for transmitting data symbols in a CDMA communication system including a transmitter having an antenna array and a receiver, the method comprising the steps of: generating a first and second data field of symbols; encoding said first and second data field producing complex conjugates of the symbols of said first and second data field; transmitting from the said transmitter a first communication burst including said first and second data fields separated by a midamble over a first antenna and a second communication burst produced using said complex conjugates of said first and second data fields separated by a midamble over a second antenna; receiving and decoding at said receiver said first and second communication bursts to recover said first and second data fields, the decoding being performed after said first burst midamble and said second burst midamble are canceled; wherein said first communication burst comprises said first data field followed by said first burst midamble followed by said second data field followed by a first guard period; and said second communication burst comprises a negative complex conjugate of said second data field followed by said second burst midamble followed by a complex conjugate of said first data field followed by a second guard period.
