Partial Transmit Sequences for Peak-to-Average Power Ratio Reduction in Multiantenna OFDM

open access: yesEURASIP Journal on Wireless Communications and Networking, 2007
The major drawback of orthogonal frequency-division multiplexing (OFDM) is its high peak-to-average power ratio (PAR), which gets even more substantial if a transmitter with multiple antennas is considered. To overcome this problem, in this paper, the partial transmit sequences (PTS) method—well known for PAR reduction in single antenna systemsâ€
