摘要:In this paper we suggest to use the ASTC (Algebraic Space Time Codes) as powerful coding technique for IEEE 802.11x OFDM standard combined with PAPR reduction scheme. ASTC with their very Algebraic- construction based on Quaternionic algebra, have a full rate, full diversity, non-vanishing constant minimum determinant for increasing spectral efficiency, uniform average transmitted energy per antenna and good shaping, readily lend themselves to high data rate situations. However, by their construction they require a nonselective flat fading channels belonging to narrow-band systems. In fact, such systems are not readily found in airs interfaces. In open air we have what are commonly called frequency-selective fading channels. As a matter of fact, it becomes extremely necessary to harness their power for wide-band systems.
