Peak power reduction for OFDM systems with orthogonal pilot sequences

Garcia, MJF ; Edfors, Ove LU and Paez-Borrallo, JM (2006) In IEEE Transactions on Wireless Communications 5(1). p.47-51
Abstract
In this paper, a novel peak-to-average power reduction approach for orthogonal frequency division multiplexing (OFDM) has been addressed. Two-dimensional pilot-symbol assisted modulation (2D-PSAM) is employed in coherent OFDM for channel estimation, and it is based on inserting known symbols spread throughout the 2D time-frequency grid. These pilot symbols are employed to simultaneously perform distortionless peak power reduction with a suboptimum technique named orthogonal pilot sequences (OPS), which reduces additional system complexity and side information compared to optimum pilot values. This proposal attains a further step over other previous works, since this set of sequences allows blind detection at the receiver without prior... (More)
