  • Method and/or system for reduction of PAPR
    Patent number: 8040787
    Abstract: Methods and/or systems for reducing peak-to-average-power ratio (PAPR) may utilize rotation among transmit channels and/or inversion of polyphase sequences of sub-blocks of an orthogonal frequency-division multiplex (OFDM) sequence in a multi-input multi-output (MIMO) scheme.
    Type: Grant

  • STBC MIMO-OFDM peak-to-average power ratio reduction by cross-antenna rotation and inversion
    Patent number: 7339884
    Abstract: A signal scrambling method is provided for peak-to-average power ratio (PAPR) reduction of STBC MIMO-OFDM signals in a MIMO-OFDM system having Y transmit antenna. In general terms the OFDM sequence of symbols in said signal for each transmit antenna is divided into M sub-blocks of equal size and subclockwise rotation and inversions are performed across all transmit antennas to generate [2Y]M permuted sequence sets from the original OFDM sequence. Based on a predetermined criteria, there is then selected from the resulting sets of OFDM sequences the one with the best PAPR properties for transmission. The predetermined criteria preferably comprises identifying maximums for all [2Y]M sequence sets, by calculating the largest PAPR value of Y sequences in each set and selecting a set with the minimum maximum for transmission.

    Patent number: RE41433
    Abstract: A signal scrambling method is provided for peak-to-average power ratio (PAPR) reduction of STBC MIMO-OFDM signals in a MIMO-OFDM system having Y transmit antenna. In general terms the OFDM sequence of symbols in said signal for each transmit antenna is divided into M sub-blocks of equal size and subclockwise subblockwise rotation and inversions are performed across all transmit antennas to generate [2Y]M permuted sequence sets from the original OFDM sequence. Based on a predetermined criteria, there is then selected from the resulting sets of OFDM sequences the one with the best PAPR properties for transmission. The predetermined criteria preferably comprises identifying maximums for all [2Y]M sequence sets, by calculating the largest PAPR value of Y sequences in each set and selecting a set with the minimum maximum for transmission.
