“…Existing of some similarities between the conventional STC-MIMO OFDM systems and STC-MIMO MB-OFDM ones invite us to more specifically analyze the latter systems. The Golden code [14] and the Alamouti code [6] represent the most known and used Space-Time Block Codes (STBCs). The Golden code, which has been proposed in 2004, has many advantages: full-rate and full-diversity space time code with maximal coding gain.…”

“…The Golden code, which has been proposed in 2004, has many advantages: full-rate and full-diversity space time code with maximal coding gain. It was shown in [3] and in [6] that ASTC code outperforms the Alamouti code in a MIMO OFDM system and in a MIMO MB-OFDM system, respectively.…”

“…the Alamouti code [5]. In [6], it Due to its spectrum efficiency and channel robustness, OFDM modulation is a very promising and attractive technique for wireless communications. However, one of the major problems which remain unresolved in the design of the OFDM based transmission systems is high Peak-to-Average Power Ratio (PAPR) related to high correlation of input sequences.…”

Multiband Orthogonal Frequency DivisionMultiplexing (MB-OFDM) for Ultra Wideband (UWB) technology presents a potential candidate for the diverse set of high performance short-range applications. But this 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 fullrank, 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. 
