SEQUENTIAL TRANSMIT MULTI-BEAMFORMING METHOD WITH LOW COMPLEXITY USING HADAMARD MATRIX
摘要
PURPOSE: A sequential transmission multi beam forming method of low-complexity by using HADAMARD matrix is provided to reduce the complexity of hardware by using the weighted value about a multi transmission antenna. CONSTITUTION: A transmission beam forming unit(130) forms transmission beam through a transmission codebook. The transmission codebook is generated by using a HADAMARD matrix. A codebook storage unit(120) stores the generated transmission codebook. A reception beam forming unit(180) forms reception beam through the reception codebook. A code book storage unit(170) stores the generated reception codebook. A spatial diversity processor(190) transmits channel information to the reception beam forming unit.
