Abstract—Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) for Ultra Wideband (UWB) technology presents a potential candidate for the diverse set of high performance short-range applications. But this scheme causes high peak-to-average power ratio (PAPR) resulting in the saturation of high power amplifier (HPA). Various techniques have focused on minimizing the PAPR for OFDM systems in the literature. These techniques can also be used for PAPR reduction in MB-OFDM UWB systems to enhance performance. In this paper we suggest to use the ASTC (Algebraic Space Time Codes) as powerful coding technique for MIMO MB-OFDM UWB system combined with PAPR reduction scheme. Thanks to their algebraic construction, the ASTC codes based on quaternion algebras and called the golden codes, are full-rank, full-rate and have the non-vanishing determinant property. It will be shown that ASTC code can provide significantly better performance, when combined with a PAPR reduction scheme.
