PAPR Reduction Using BPSO/PTS and STBC in MIMO OFDM System

The growing development of the telecommunication world increases the need for spectral resources, especially that those are more and more rare and expensive, so the use of the multiplexing techniques in particular the modulations multi-carrier is thus a very useful mean to better optimize these resources. Several techniques permitting a better use the spectral band of the channel exist, such as that Orthogonal Frequency Division Multiplexing used in wireless communications systems. Therefore, the Orthogonal Frequency Division Multiplexing (OFDM) is reputed favorable, due to the security level it offers and its great resistance to the interferences, for the most of telecommunications technologies like the DAB (Digital Audio Broadcasting), the Digital Video Broadcasting (DVBT), and the Digital Asymmetric Subscriber Line (ADSL), etc.
